Why are all the Silverstone F1 heli’s using a call sign starting JKY or JCKY?

As the title, noticed all of the helis flying around Silverstone using this callsign following with a number. Recognised specific heli reg’s that normally fly under different call signs including a neighbour’s heli he often charters.

Any chance someone can figure out what this is?

Didn’t get outside in time and only saw two contrails, so I’m guessing it was either two planes or a bigger one?

NASA806 (N806NA) U2

Just managed to catch the end of this exceptionally short flight for the Dragon Lady!

I've also included screenshots of it's recent flights, the last few being notably short 🧐

Possibly testing some new equipment?
