According to a new NTSB report, Roy Halladay was flying dangerously close to homes and making wild turns, and adjustments in altitude before his fatal crash.

The GPS data pulled from the plane indicates Halladay was climbing, then diving around the crash site. The report goes on to say that he at times was “as close as 75 feet to the Gulf Harbor South Beach houses.”
