Flight have already had their Typhoon flight, and gave it to Craig Hoyle, their defence editor (good guy, great communicator, sharp mind), and not to Pete Collins.
They can't really expect a second bite at the cherry.
And perhaps EF GmbH thought that Collins' Rafale flight test lacked credibility, and didn't feel that a pilot who retired from military test flying 20 years ago, and whose most recent frontline tour was on the Gen 1, steam driven, analogue Harrier might not be especially well qualified to evaluate the jet?
