Not too sure what's happening but I live near Teesside Airport and two FRA Falcoln's who do the Electronic Warfare training took off and flew past our house at fair rate of knots before joining up and just picked up the ASTOR aircraft as well.
I had a look on one of the Falcoln's a number of years ago and the stories some of the crew had were amazing....
Also they said they had great fun with what seemed a fairly simple setup as well, an AOR3000A scanner and a minidisc walkman. Apparantly they recorded air-air and air-ground transmissions then edited them and played them back to confuse the pilots!
