Hehehe, I was in that programme. They filmed it at Bournemouth Airport, mostly at the museum where they have a BAC 1-11 (they were built here). The extras did not turn up one day, and I was not flying due to the miserable weather, so when they came looking for bodies I volunteered. I was on the investigating panel for the AAIB, didn't say anything but looked shocked a few times and wrote things on a piece of paper.
The windscreen had previously been fitted with bolts one size too small, and when they came to refit the new bolts were selected by eye, comparing with the old, and were in fact even smaller. The engineer was advised in the stores that he was looking for the wrong size of bolts, but insisted he was right. He then did not match by sizer number, at least that is how it was depicted fliming the board.
