I would have been in the scene where Crossfield is being congratulated by Yeager; the newsreel footage. I would have been in the very back with a 1950s crewcut, Ray-Ban® Aviators, and a white lab coat.
Don’t bother looking. Believe me, I scanned that scene very closely!
I was almost in the scene where Royal Dano comes to the pilot’s house to give the new widow the bad news (at the beginning of the film). I and another guy were dressed in khakis as Air Force sergeants and we were going to drive a Jeep in the background, but the Jeep wasn’t used.
I was “sort of in” one scene: Where the X-1 is being readied for its historic flight. It was a little breezy that day and they had three of us get on the off-camera wing with our legs pulled up to prevent the plywood mock-up from rocking. So I’m in the scene, but hidden by the X-1! 
Okay, so they didn’t use a real NF-104; but they could hardly pull the one off of the pedestal at the Test Pilot’s School! And the F-104 they did use was really pretty. I didn’t get to see it during the filming, but I did get to hang out in the hangar with the T-33s and the F-86s.
Chartoff-Winkler Productions put on a good feed, too. Like, filet mignon for lunch. Pay was minimum wage ($3.45/hour at the time) but I had vacation pay from my job with a contractor in Ridley Mission Control Center. After filming at Edwards, they had a wrap party at the Essex House (now Ramada Inn) in Lancaster. Good food, friends from work, chatted with Levon Helm, and the production crew made all of us extras feel like an important part of history and the film.
As for my co-workers, my boss (the late Gary Hall, a former test pilot and – I think – one of the charter members of the Test Pilot’s Association) might be glimpsed in one scene, but I’m not sure. A girl I work with danced at Pancho’s, and you can see the back of her blonde head at one point.
The Right Stuff is one of my favourite films; not just because I was (almost) in it, but because I was at EAFB as a very very small part of testing new aircraft.
(Remind me to tell you of the time dad picked up Chuck Yeager when the general’s AC Delco ultralight was forced down in the desert.
