Cold War Jets

In around the year 1988 my friend and I travelled to the back garden of someone in the village of Mildenhall to camp for the weekend. The purpose was to spend the weekend at the Mildenhall airshow, which I had been to before but was important for a few reasons:

Aircraft
Military aircraft
Military might
Blackbird
More planes

When you are a plane nut then airshows are where you get your kicks. I can’t help what I like and planes have troubled me all my life. It’s possibly due to growing up underneath the flight path of Stansted Airport in Essex. It could be because of my dad who was involved in the industry when I was young or it could just be that an aluminium tube filled with people and fuel doesn’t really have any business being six miles up off the ground.

Somehow Alan and I had found the number of someone who lived near a walk-in entrance to RAF Mildenhall [actually a USAF base] and we had booked to camp in her garden. Then, each day of the show we walked in. My memory of the charges is not great but I seem to think we got in for something like £5 each whereas a car for the day was £40. I suspect those prices are wrong given what prices were like in the 80s but I can’t remember. I do know it was dirt cheap to walk in to the show rather than drive.

There’s only a few things I can remember from the airshow. I sort of remember the Blackbird flying, it was a privilidge to see that. I also remember both AB and I watching a helicopter display, possibly an Apache, when it did a form of a wing-over or loop. Both, AB and I were amazed and clapped. There weren’t many who joined in the clapping, only those in the know.

The Red Arrows were there, of course, I I’m not sure if this was before or after I had been to Cyprus, porbably before and so I was still excited by them. The above photograph was beautifully timed by me.

My father must have found the original negatives of these photographs as he has scanned them inot his computer. I suspect there are some more picture lurking in a box somewhere and I’ll have to keep scanning his computer to see what I can find.

Here are some more photographs from those days. They aren’t very good but them photographs weren’t back in the 80s. I wasn’t great with a camera and with only 24 or 36 shots on a reel of film you were very limited in what you could take.

Sea King @ Mildenhall
Harrier, A-10 and A7 [?] @ Mildenhall
F-5, F-16, C141 and AB @ Mildenhall
EF-111 [?] @ Mildenhall
SR-71A @ Mildenhall
Phantom @ Mildenhall

AB and I had a great time at the airshow. It was a really good experience and well worth the camping and entrance fees. I do feel it’s a bit of a shame that the number of airshows has decreased over the years, but these beasts were probably also a show of strength during the cold war. They were interesting times and maybe I should be glad we don’t currently need massive forces to prevent mutual destruction [it feels like it’s heading that was again though].

Addendum: I have had confirmation of aircraft types from a US source:

A7 is indeed an A7D and it will have been a Lynx you saw display rather than an Apache.

Forts Position

On Saturday I went to visit the Redsand Forts. There are a couple of things I’d like to note for you.

Firstly I use the opportunity to calibrate the altitude on my Garmin Instinct watch. I usually give it a go each month, just to make sure it’s working properly. While out near the forts I used the calibrate with GPS option and I got an altitude of -2m. Initially this confused me but then I realised that I was close to the sea but during low tide, therefore I was likely negative AMSL, so -2m seemed about right.

The above picture is my position as saved by the Garmin Instinct. I didn’t even know that was an option but I noticed it while I was calibrating the altitude. I saved the position and then was able to display it on my phone. There’s a Garmin app called Explore and I like the functionality.

While out on the sea I also used Google Maps to see where I was.

I took this screen shot a bit before the Garmin one and so you can see I am slightly further east than the previous picture. I don’t think either of these was taken at the Redsands Forts complex as I was too busy watching.

Cranes On Boats

While walking along the wharf before I went to the cinema to see The Matrix I happened upon some cranes on boats. Now, I know technology and science stuff but cranes on boats still amaze me. They shouldn’t but they do.

Above is a crane on a boat. That’s pretty impressive. What could be better than a crane on a boat? Well, surely a boat being held by a crane on a boat:

Also, as a bonus there are two cranes on two boats. I think this could turn into a minor fascination along with my occasional series on safes! Having glanced through these esteemed communications I can see that my series on safes didn’t even mage these pages. I’ll try and correct that.

Kurtz Got Airbourne

This photo shows me in the rear seat waving at the crew room as the Juno helicopter taxied past before landing. I’ll thank OM for this photo. The Flight was easily the best fifteen minutes of the year so far, I can’t see it being outstripped either.

Fg Off Parish waving at the crew room of the DHFS — DHFS – Wave

The DHFS uses two types of helicopter and both are pretty much Eurocopter versions painted similar to all others! I’ve found it hard to tell them apart but after examination the easiest difference is the engine intakes. The Juno has intakes flush with the bodywork whereas the Jupiter has intakes mostly vertical in shape and they stick out more, the engine exhaust is more pronounced. There might be a slight difference in the landing skids too.

Juno and Jupiter — This was stolen from the MOD RAF website.

Untruth

There’s been quite a bit of moral outrage recently at the Jeremy Kyle show and that it should be removed from television permanently. I haven’t really paid attention to what has happened, as I understand it someone died and the show has been stopped from broadcasting for a while. Newspapers and social media have been very loud about how the show should be pulled completely.

Why does it take something bad to happen for people to be open about what they think is right and wrong? All of this moral outrage wasn’t there two weeks ago when the Kyle show was still on television. There wasn’t anyone loudly calling for it to be stopped. It took the death of someone for the media to declare that they thought it was a bit shit all the time. They did fuck all for many years.

This is strange. This effect that it takes a large news cycle for the media and opinion makers to declare something as bad even though it’s been around for years. What sort of behaviour is this? Where was all the complaining before something terrible happened? I’ll tell you what, it wasn’t bad enough for the media t give a shit, but that someone died before they spoke was terrible.

I have, in the past, watched a lot of Jeremy Kyle. I used to think it did some good. I thought that it helped people to talk to each other in a safe space when the rest of the world didn’t give a shit. It allowed the chance for people to communicate. I was probably wrong to think this. We shouldn’t forget that Kyle is a television show. It’s there to entertain and make money at a basic level and it probably did little to help its stars.

My biggest problem with the Kyle show was the use of a lie detector. Here was have a television show with a purported “helping people” theme and they relied on the utter bullshit that is a lie detector. The polygraph doesn’t work. It’s incredibly difficult to tell when people are lying. The TV show used the lie detector to try and solve family issues, people’s future relationships relied on the results of a flawed piece of equipment. Families will have been broken up because of the reliance on the polygraph and its results.

The idea that the show declared the truth or lies as fact was an appalling use of a bullshit piece of theatre – the polygraph. It doesn’t work. I guess the show tried to disclaimer the use of the detector with an on-screen caption saying that “it doesn’t work but some people believe it”. That’s what religion does. It’s horrific the hurt and separation using this device caused.

Do you know why polygraph results aren’t permitted in UK courts? It’s because they don’t work. It’s incredibly difficult for humans to tell when other humans are lying. I’ll let you into my reasoning.

Humans learn from toddler age that lying works. The individual will receive rewards for lying, as long as they can keep that lie going. Humans have spent their entire lives lying at times. This behaviour is learnt and used almost constantly. Little lies are easy. Larger lies are more difficult but they get easier with time. It’s amazingly easy to convince yourself that something happened when it didn’t. Human memory is terrible. Eye witnesses shouldn’t be allowed in courts but that is for another time.

I’ll give you an anecdote, which isn’t evidence, but it personalises the story and allows you to connect rather than just concentrate on the plain facts.

Years ago I ran over a pothole on a bend in the road near my village. The weather had been incredibly poor and there were potholes all over the place. The sudden compression on my left front suspension broke the spring and by the time I got to work the other spring had broken through excessive weight on it.

I tried to make a claim through the local council for the damage, claiming that the road was in poor condition. However, I didn’t want to take photographs in the road where the pothole was, it would not be safe to take measurements on that corner. So, I took photographs of a pothole just inside the village, it was of a similar size and depth and along a route that I drive. To ensure that, if questioned, I referred to the nearer pothole I kept going over the story in my head. I also visualised my driving the car over that pothole over and over. I talked through the story while walking the dog and basically formed a memory of me breaking the car by driving over the pothole near the village.

Even now, after more than ten years, if asked I would immediately respond that the pothole was in the village. I would then question myself and remember what had actually happened. With just a little understanding of human memory it is easy to adjust what we “know”. Memory is fascinating and terrible. Humans are terrible.

It’s Dying

We all need distractions I guess and maybe laughing at the poor on the Jeremy Kyle show was one of those. It was a way to feel better about ourselves, a way of looking at people who suffer and try but ultimately are just a passing fad for those of us who are OK at the moment, thank you very much.

Perhaps that’s why people watch bollocks like Eastenders and other soap operas where everything happens to everyone because if everyone tried to get along and be nice to each other it wouldn’t be worth watching and it wouldn’t provide escapism.

I’m certainly clear in my head about why I like science fiction. It’s nerdy and requires a little science knowledge but space type stuff often provides a glorious distraction to the mundane. It gives me the chance to live elsewhere and think about the implications of travel and technology that won’t happen in my lifetime.

In reality it’s all fucked isn’t it? Brexit, politics, the planet, it’s fucked. It’s dying. The single GREATEST threat to the human population wherever you live at the moment is the fact that the world is on fire. It’s really depressing. I’m hoping I’m dead before the Water Wars start. They are going to be terrible.

All those politicians worried about maintaining power and trying to get your vote using short-term gains and short-term give-aways. Not one of them is standing up for the planet. We need RADICAL change to society and how everything works. We need to save this planet. I’m not normally pessimistic about things but the planet is dying through human abuse and it’s going to kick us the fuck back and quite rightly too.

I’m scared for the future of my children and the fears that they will face as they get older. I’m scared for my unborn descendants because it’s all going to be shit. Take a look around the world and see where the action is to provide a future for people on this planet. It’s not there. Consumption-capitalism is driving this world to ruin while at the same time killing those who are poor and have little. It’s disgusting. We should be promoting a social-environmental-capitalism. Governments need to incentivise social and environmental good-doing.

It’s not like this is new. We’ve known about climate change and carbon emissions for over forty years. NOT a thing has been done in my life time that will drastically alter the way the planet is going to react. It’s all a nightmare. I’m not sure humans are mature enough to do anything about it either. I’m hoping that the generation after me, once they assume power when the baby boomers and generation X die off can cope and end up being nice to each other and working to create an Earth for the future.

I see the newer generation of politicians kicking back against the obscene capitalism of the last one hundred years and are now talking about social responsibilities and they seem to be speaking a more gentle kind of politics trying to go after the aging fuckers who have taken everything they can and created personal wealth beyond necessity. Here’s hoping that people like AOC can start to change the world to actual care about each other.

In the mean time the Daily Mail and other institutions that gain their power from the want and blinkered view of the older generations print articles implying that solar farms are wrong and will ruin your view.

The headline should have been “locals fight planet saving solar farm (stupid cunts)”. But then the exact people fighting this farm and the ones who read the Mail because they are all old and white. Fuck the Mail.

More amusingly, in thirty years the Hardy countryside won’t look like that at all because the climate will have changed so much it’ll be barren and all the locals will have died of malaria.

War Machinery

Took a few hours out of the busy schedule the other day to visit the Historic Dockyard at Chatham. This is one of the places this country built and serviced warships for over four hundred years. I found the positive spin put on it all in the introduction video to be full of cognitive dissonance but I guess that’s how it goes. It was rather “Great Britain ruled the seas and controlled the world” it was kinda a Brexiteer’s wet dream with promises of glory and power. It completely ignored the human aspects and damage this country has done around the world. Anyway, enough from this old lefty, let’s have some pictures.

I like the way the light enters this room. It’s part of a building that contained the first smithery. There were a few buildings like this where all the metal work was completed. It’s quite impressive.

HMS Ocelot is a spy submarine and the last Royal Navy ship to be built at Chatham [they built more afterwards, but for other countries’ navies]. It’s quite impressive being given a tour around this beast. I think I’d love to see a more modern submarine, the whole concept of living under the sea is rather freaky.

HMS Cavalier is a destroyer now permanently moored in wet-dock at Chatham. I would have liked to have seen the engine rooms and murkier areas of the ship, but that would probably need specialised tour guides and so this one is a self tour.

It’s a great place to visit and I have been here a few times in the past. I’m not sure if I’ve written about it before though. I’ll go and have a look! well, my cursory search has highlighted no references within this website to the dockyard, that seems strange but there you go. This is the first. It’s a lovely day out.

Early Air Pioneers

Until about four days ago I didn’t know that the first powered flight of an aircraft in the UK occurred on the Isle Of Sheppey. The island isn’t that far from here and so I went to have a look at a beach.

Upon some investigating it turns out that the first purpose-built aircraft factory was on Sheppey and built by the Shorts brothers. Then it turns out that they then build the first airfield nearby in 1909. This is amazing and I don’t know why I didn’t know this before this week.

I had previously known that Shorts used to make aircraft at Rochester and used the Medway there as the aerodrome. It is here that they made the Sunderland and other famous planes.

Eventually they moved production to Belfast and now the company is known as Bombardier. It would have been magnificent to see sea planes taking off and landing on the river Medway, such an age of exploration and adventure. This would have made Rochester such a target during the second world war as there was a Royal Navy shipyard and also an aircraft manufacturer there.

On Sheppey I drove to the old RAF Eastchurch site which is now three prisons built on Crown land. It was strange driving to the museum as there was lots of security along a public road. It felt like entering an RAF base. Two of the prisons there are high security and the walls were impressive. The third prison is an open prison and the museum is on the land of that prison with a cafe nearby run by inmates.

The key to the things I have marked in the above photo runs such:

The museum
The first aero hangar in the UK
The RAF base water tower
The original airfield control block
The E-W runway
The N-S runway

There are plenty of features there to see and the person running the museum was really friendly and told me loads about the history. It’s strange to me all these old air force bases that are now re-purposed. I guess I hanker for the old days of aircraft everywhere.

One of the buildings on the site still shows the scars of war with bomb damage on the brick wall:

The museum is based in one of the original base buildings and certainly contains lots of lovely information about the early days of aeronautical exploration in this country.

Inside the building was a photograph taken at Muswell Manor on the east coast of the island and one of the early headquarters of the Royal Aero Club. In that photograph the following people are pictured:

The Short Brothers
Frank McClean
Frank Hedges Butler
Warwick Wright
JTC Brabazon
Wilber Wright
Orville Wright
Charles Rolls

That is an amazing collection of rich people who had the money to start the aviation industry in this country and the world. The Wright brothers had come across the Atlantic with their flyer to try and create interest and also start manufacturing the product. This they managed and the Short brothers built the Flyer under licence. The rest is pretty much history as we know. I hadn’t even been aware that the Wright brothers had come over here!

Near Muswell Manor is a statue to the Short Brothers. It stands as a marker for the start of aviation in this country and the adventuring that started at Shellness.

Not A Neo Con

I found an advert which, I think, lies! I was looking through the newspaper that my parents read and I found the advert below. Now, let me first explain that I do not agree with the “news”paper that my parents read and given my personal politics it stresses me that they still get this heap of shit delivered to their door. I have offered to pay for a different paper but they have refused. I’m not sure why they still read the Express but it is a vile piece of work.

This advert is along the lines of what started me into this skeptical hole in the first place. Originally my father gave me a magnet that surround the fuel line in a car and then magically makes the car engine more efficient. I’ve written about it here. At first glance it seems reasonable that something might increase the fuel efficiency of an engine, but if it’s that simple don’t you think the manufacturers would do it anyway?

I wrote about a fuel chip I saw advertised in a motorcycle magazine here. It seems that this device is making very similar claims. Notice that if you want, you can get your money back if you aren’t happy with the results. This is a classic scam because no-one cares enough to ask for their money back.

Having looked at the website in this advert and the one for tank chip they both are in association with the same company.

Hamilton Direct

This company is based in Paignton in Devon. They seem to peddle a lot of bullshit. Don’t buy anything from them.

The bike insurance people Bennetts did a proper testing regime on the tank chip and they found it makes no difference. You can see their results here: Bennetts.

If the product seems to good to be true then the chances are that it is.

Mutability

A few summers ago my project was to build an ADS-B receiver and use the data collected to upload to an aircraft tracking website. If you want to see what I see then go to:

360 Radar

I don’t remember the details about how I found this but the project was good fun and I got the Raspberry Pi in the loft with a decent aerial, filter and pre-amp, and it was all working fine. I was using a lovely piece of software called Virtual Radar Server and was able to use this as a web server and people could see the aircraft on web pages served by the Pi.

360 Radar is good because it using multi-lateration to detect the positions on military aircraft. This is pretty handy for spotters like me and it also works well when I take cadets to RAF Wittering for some Air Experience Flying, I can see where my cadets are in the air.

Over the last few months I’d been receiving outage warnings from the 360 guys. It would appear that my Pi had stopped sending them data and while I live in a flight-busy area of the country and there’s plenty of contributors here every little helps. I had the occasional outage and this seemed to be when the router reset and the Pi wouldn’t re-find the existing wi-fi network. I just had to power cycle the Pi and everything worked fine. The outages seemed to be occurring more over the last while with the Pi stopping feeding every few days.

At first I thought it was a wi-fi issue so I bought some new ethernet-over-power adapters and linked the system into the route via a wired connection. This also meant I could ssh in to the Pi even if wifi was the original problem. I tried to work out how to turn the wifi connection off entirely but just ended up changing the SSID the Pi looked for as a simle way of ensuring the wired connection took preference.

After a week of testing I was still getting outages and my initial thought was that the VRS software was making the Pi work too much. I’m not sure why I thought that but I looked up ways to remove VRS. This was not the easiest as I had installed it years ago and couldn’t remember how it ran within the OS. I eventually managed to remove the Mono service and this stopped VRS running.

It was at this point I worked out how to use the log file of the MLAT client and I could see that all the software seemed to be working fine it was the Dump1090 program that didn’t seem to be sending data internally. I figured that Dump1090 had somehow stopped receiving the signal from the aerial. It all worked fine after a reboot and so I decided to replace the USB dongle that was decoding the ADS-B signals. I ordered a FlightAware USB stick and at the same time decided I would rebuild the Pi OS from scratch to have a “clean” build.

Once the new USB stick arrived I turned off all the systems and followed the excellent instructions from the 360 Radar guys to rebuild the OS of the Pi and just run a lite version of what I had been doing before. This took a while as I mistakenly thought the Pi wasn’t uploading to 360 because I was looking at the wrong server details. After an email to the support chaps it turned out I was contributing and a couple of hours of troubleshooting by me hadn’t been worth it!

So, the Pi sits in the loft, chugging away supplying data to 360 Radar, in return for which I get free access to their excellent tracking site. I’m running dump1090-mutability along with the MLAT-Client from 360. I’d really like to be able to allow you all to see the output of this but Mutability doesn’t have an external feed and I am not opening up my 80 port for the world.
