My old man used to be in REME (Royal Electrical & Mechanical Engineers - could explain where I get my geek from) and he was in charge of the Andover Aero Club (aka the Army Air Corps) so I got to fly in lots of choppycoppers when I was a lad.
He then left and joined Westland who produce the WAH 64 pictured above budgie ^^ and I've had a ride in one of those - still doesn't stop me shouting at them when they fly in formation over my house at 200 feet at 1am.
My uncle was an observer (who sat in the 'coal hole', under the flush-fitting canopy to the right of the pilot's position) in Sea Vixens throughout the '60s, and was possibly the only person to have been a part of both Fred's Five and Simon's Sircus. I got my love of 'planes from him, and numerous visits to the Yeovilton FAA museum as a kid. The Vixen is something else, and what the RN had the pilots and observers do in them beggars belief.
Second, the Avro Arrow
Never mind being one of the most advanced designs of the 1950s (yes, really, 1950s!) this 'plane would have been advanced even into the 1970s. Sadly killed by Cold War politics and money.
Finally, the Bell 206 JetRanger
Because you have never been so pleased in your life as when you hear it coming over the hill and you realise that's it for another day. Because I trust them. Because the pilots we use at work are amazing and can do things with these puppies that you wouldn't believe. The pick-up truck of the North.
Me 262 had problems with thrust stability, and due to its lateness of entry it could never be redesigned or corrected in time to change the War.......Pilots have said that the Me-262 would throttle up and just explode for no apparent reason, this was later admitted by developers of the plane, increase in fuel intake and thrust often meant a unpleasent boom.
I have to agree with all of the previous, but I always used to look forward to the sight of this when I was cold, hungry, knackered and fed up, often it was taking me back to where this pic. was taken from.
