At about 16:50 Pacific time, a Beech E33A landed gear-up during an aborted takeoff from the Lake Tahoe Airport. The four occupants were uninjured. The pilot said he took off from runway 18 and the airplane accelerated normally. He rotated and raised the landing gear. The airplane refused to climb, however, with witnesses saying it was only about 30 feet high by midfield. The pilot reduced power and selected gear down, but the airplane settled before the gear extended. The density altitude at the time was about 7,700 feet.
