Flares at Heathrow
I was on the Heathrow perimeter road heading East toward the car hire collection place and watching a BA 747 coming down the approach to 27 Right when what I can only describe as a flare going off with a bright white light went off over the threshold of 27 Left (nothing on approach). This was followed about 20 seconds later by another one. This was at 06:06 on the morning of the 2nd August.
Was this some clown with some rockets or is it part of a procedure?
