They were two "Dominies"(HS-125's) from RAF Cranwell here on a courtsey visit,(hence the golf clubs and civvie bags that came off the a/c). Theyre actually Sim trainers for radar operators for the likes of Tornado crews and the likes, hence the different noses on them compared to normal HS's.
A Hawk from RAF Valley was supposed to arrive on Fri but cancelled at the last minute, DOH!
There was also a USAFE C-21 (Learjet) in over the weekend.
I see one of the CASA boys didnt waste much time in posting photos of the above on the site!!
