The early 90s had both the RAF and the French Air Force buying new airborne early warning aircraft in the form of the E-3. Unlike the USAF and NATO jets, these included the upgrade to the CFM56 engines which improved endurance and performance. I saw the RAF’s jets on many occasions but never encountered a French jet until this year – after the RAF jets have been retired and not long before the French ones follow suit. I’m not sure how much longer they have but seeing one arriving and departing the show was a nice result. I was pretty happy that I happened to be at the arrival end when it came in which was a bonus.
