Airprox?
 

Hi all. Not really for this forum, but was sitting static in my car in Ewell today on the phone. Looked up and saw what looked like two heavies diverting from converging. Difficult to judge altitude difference, reckon both must have been in the region of 10k ft. I know that it was fairly close to heathrow. Both appeared to be climbing. Both seemed to be aligned. Could this be my error of judgement? I'm often in that area and never seen that before. Anyone have any ideas?

Think you're right bru, not really for this forum
