Aircraft that was tested in the UK

Hi,

I'm searching for information of a aircraft test in the Uk. I was reading about it 2 years ago. As far as I can remember, there was an NKC-135 Involved. And when the ATC Controller asked the 135 Pilot what they were doing, the 135 Pilot said, if you want to keep your job, be quiet or something like this. And after that he said something the NKC Pilots usually say when they refuel a new aircraft for the first time. Anything with chicken... lol Cant clearly remember.

Now I've wanted to know if anyone has some more Informations and/or Links.

Any help would be appreciated!

So, no one has any idea? Should have happened in the 90s.
