Exactly. It's not how many are on board that matters, it is how many below that can harmed that counts.
Even a single seat Cessna into a football stadium would be catastophic. As an example (not withstanding timing) weren't Chelsea at home that day? A potential audience circa 40,000 people in a relatively confined area just a few miles east of LHR.
Did this aircraft actually fly over LHR at 7000' whence it made the sharp turn onto north? Somebody either instructed it to go that way or it did so of its own accord. Does anyone know which it was?
