USAF Participation
The various British Empire air shows, during the first half of the 20th century, were impressive, to say the least! Even up to 1962 there were huge numbers of exciting aircraft and massive formations (or so I'm told). I'd be interested to learn if the USAF were invited to participate in those.
My own experience of air shows between 1970 and 1989, at Finningley, Leuchars, Church Fenton and Abingdon (I never made it to a Biggin Hill air show, more's the pity) was that lots of European air forces and the USAF all contributed flying and static displays. Lots and lots of people turned up and traffic clogged up all the access roads for miles around, both on the way in and on the way out. Nonetheless, everyone seemed to enjoy and have fun.
The yanks were great on the ground and in the air (and in the mess). Lets hope the RAF and the USAF don't lose touch with each other.
