Don't forget there were two of them (aircraft), one landed to try help the other..........the Norfolk coast has a range call RAF Holbeach (check Wiki) ...........can't say it was destination, but it is a live firing range, not sure if its used at night, but has certainly been used by Pave Hawk before..........I would have thought an operational Recon / Search unit would need night time flying training on a regular basis to keep operational.
I can't see the 'unusual' in this , especially when Norfolk and the USA are involved
