You challenge was to name one, not currcumvent the circumstances! It can happen in good or bad weather. If he lost hydrolics or had a major heart attack it sure as hell can happen on a sunny day. The pilot is reported to be 70 years old BTW.

News is reporting that the pilot sent a message to control tower saying he was having problems navigating the plane and sent out an SOS - so there you have it - it was a very freak accident. Not a terrorist attack of any form. It happens - rare but it happens

The flight plan, I'm presuming, was filed by the 70 year old guy. Have they found his body in the skyscraper? If not, have they searched the airport he took off from?
