i saw something awesome over clapham common once. I was with a table load of people and we all looked up going whaaaat? I think in the end we decided, as there was no headlines anywhere, not a mention. that it must have been meteor burn up. seems lame tho because it was not only large but way slower than a shooting star. cruised right over us, for definate was not a plane. We were spooked for a while. I made a quick call to the interplanetary society and was told naah just a firework probably.So,forgot about it. As you do. I remember how i felt like a character in close encounters for a while there. Met someone once who saw a large v shaped thing over his head that had odd symbols on its underbelly. he got obsessed and looked them up. Closest he could find was ancient egyptian symbols for 'wheat' . Gets you crazy.
