Saw two small objects trailing in very loose formation westbound over Woking yesterday afternoon - "aha!" thunk I. Nope, a pair of US registered Falcons, a 50 and a 2000, a 1000' vertical separation and probably a mile or two horizontally - looks they diverged after Compton, the 2000 descended towards Dublin, the 50 went more westbound and looks like it popped into Shannon.
