You mentioned the war? Did you get away with it?My first employer built radars for fast jets; had a reputation for running late, but delighting the user (RN/RAF) rather than the customer (MoD Procurement) - in contrast to our main competitor, who met every requirement of the customer, while leaving the user unimpressed ("but it's what you asked for").
At the start of the 90s, our mob won the contract for the Typhoon radar. Fairly soon afterwards, we had the International Air Forces Field Team arrive on site; regular service personnel from RAF and Luftwaffe , mostly SNCOs, employed to work on site next to the engineers designing the new kit (we may have poached one or two of them onto the design teams).
 The Luftwaffe engineer bloke had "GAF" on his ID Card. When asked "What does that stand for", he answered "German Air Force - we weren't sure that you would understand Luftwaffe". At which point there were smiles, as people pointed out the air raid shelters still lined up next to the front gate...
