V22 in Mlitary formation past Stansted
Spotted at approx 14h45 LT: two Police helo's, two large Sikorsky type helo's (CH53's?) and a V22 in formation passing Stansted Airport/ Bishops Stortford heading approx Southwestwards. The V22 in "slow cruise" with rotors half tilted. Looked like a US Military formation under escort?
Any info?
