RE: Mid-Air

T5,

you state a convincing case. I don’t know about it being just London’s skies either. I suppose there is a certain statistical inevitability that one day two airliners will meet in the skies over a major population centre either through human error or some kind of systems failure. I think the crash of the EL AL 747 in Amsterdam shows how bad it might be. On that day the loss of life was nowhere near as bad as it could have been.
