Interesting aircraft - what have you seen on your computer today?

[treadigraph]

Looks like QRA Typhoons heading out of Coningsby south towards London at 41000' and 570kt... just passing Potters Bar...

Well first one was trailing, may have been a second but couldn't see it. Fairly loud once passed. Now heading SW. Passing Alton.

Ah! Tanker standing by over Cornwall, presumably a practice alert!

Edit: it/they have gone discreet, presumably in contact with the tanker which is stooging WSW at 20000' over Bodmin Moor. Would be a fine sight from outside the Jamaica Inn were it not shrouded in drizzle...
