I don't think it changed the world, a very old plane had an electrical fault. A very sad event to be sure but not an unprecedented one.
Cover-up my arse. It's hard enough to keep a secret between two people, let alone hundreds. THAT SAID, has anyone seen that photo of a couple arm in arm on the deck of an outdoor restaurant on Long Island that night (the photo even has one of those nasty-looking digital camera date stamps on it)? Clearly (albeit in the far distance) in the sky: a missile. Don't know what to make of that at all.
