The last one for now is an F15E from RAF Lakenheath. in the mid 80s i refurbished the firestation there, it situated on the edge of the airfield Quote Link to comment Share on other sites More sharing options...
NoBodyImportant Posted August 1, 2019 Report Share Posted August 1, 2019 Can’t have a plane thread without the F22. Hands down the sexiest plane ever built. I saw one take off and go straight vertical out of sight. Great pictures, that German tornado looks good in that paint. 2 hours ago, hedge said: Lovely pics. Can't believe the Phantom is still flying. That's a Viet nam era warbird. I did RIAT about 3 years ago and enjoyed it. I also really enjoy Flying Legends at Duxford. No jets but lots of lovely sights, sounds and smells. Have you ever seen a phantom up close? They look like someone built them in a garage. Literally pop riveted together like a dirt track race car. Overlapping panels and all. Quote Link to comment Share on other sites More sharing options...

KB1 Posted August 1, 2019 Report Share Posted August 1, 2019 2 hours ago, RockySpears said: (hence the lift as the plane is "pushed" into the low pressure air by the high pressure air below) Would agree with most of what you say, apart from this bit…… The top of the wing is shaped to cause low pressure which in itself generates lift. Both + & - pressures lift a plane. Quote Link to comment Share on other sites More sharing options...
RockySpears Posted August 1, 2019 Report Share Posted August 1, 2019 KB1, Thought that is what I said really; or meant anyway. The faster airflow (faster due to aerofoil geometry) over the aerofoil causes low pressure above the aerofoil and so the high pressure "pushes" the wing up, or the low pressure "sucks" the wing up. Still great pics, RS Quote Link to comment Share on other sites More sharing options...

Still great pics, RS Strange thing, aerodynamics….. physicists still argue about it to this day🙄 When I used to fly, I was taught Bernoulie's law, and these days that is somewhat scorned on, as Newton's law is offered as a preference. Truth is they both work, depending on numerous factors…… Now that I'm in structural engineering, I find that Bernoulie's law is still favoured for calculating negative pressure effects on buildings….. YES, they are great pics👍 Nice to see a topic of such interest….. Quote Link to comment Share on other sites More sharing options...

Don't some lenses have image stabilization? Yes many lenses have IS, but it uses battery power and slows the focusing speed so is turned off on mine.

This year I took a 72 year old plane enthusiast and showed him some places he has never been before, he got some cracking shots too. While it is raining i might just post a couple more.

TIGHTCHOKE Posted August 3, 2019 Author Report Share Posted August 3, 2019 Here are a couple more, British Airways currently have 3 of their fleet painted up in historic schemes. This Boeing 747 is painted to represent the first Jumbo that was operated By British Overseas Aircraft Corporation, a company that was evntually merged in to British Airways. The Red arrows made 2 passes in formation and in one shot you can see Red 10 flying a photgrapher around to captue the uniqe occaision.
