Interesting projects.......
When I was a vac student at Farnborough in 1979 the section I was with (Acoustics) had a project involving experimental work at Thurleigh. Long story short - microphone(s) mounted in a 6ft dia polystyrene sphere, suspended from a Wessex, under which flew a BA Tristar. I think the idea was to measure engine noise shielding afforded by the wings.
Boffins, eh?
