You've been in a brilliant place. I worked where the equipment was designed and manufactured to generate breathable air from whatever was outside for the Tornado and for lots of other NATO fighter aircraft. So you might have been buying from us.
Tales abounded in the staff canteen (having a staff canteen dates the event, I think) One of my personal favourites was along the lines of "An airspace control RADAR operator in the '50s was horrified to see a dot hovering, suddenly start moving a great speed then accelerate to an impossible speed" It happened again and again. UFO? No. Top secret lightning under development and on test flights that no one admitted were happening. A vertical climb appeared on 50's RADAR as hovering. Levelling off after the climb, the aircraft's dot was moving quickly - because the aircraft was moving quickly. Then it accelerated to a top speed probably higher than any aircraft in service with the RAF today. The 50's operatoor would regard it as a completely impossible speed.
Wow.
