For Those With An Interest In Military Aircraft: Military Flypasts over London 
Link: IanVisits – Military Flypasts over London in 2011
Flypasts as listed on the website this evening:
Collating details as they are published of the various military aircraft flypasts over London and local area, as I do – and it is about as ready as it is likely to get.
Apart from the big flypast in June for the Queen’s Birthday, there isn’t a lot this year to see. I guess we Londoners were a bit spoiled last year due to the 70th anniversary commemorations.
Most of the flypasts are by the Battle of Britain Memorial Flight, and sadly, nothing over London by the Red Arrows – although they are in the South-Coast area on the Queens Birthday, so I’d expect them to pop over to London for that.
