sentence1: After the aeroplane pulled up abruptly, it then pitched down at an angle of 31 degrees, rolling left and right, partially upside-down. This sort of stall is known as an aggravated stall, and it can be very difficult to return the aeroplane to normal flight from one. In this case, the pilot had less than two thousand feet to do so before the aircraft crashed into the ground. The pilot's training has now been put into question, and it was discovered that the captain, Marvin Renslow, aged 47, had logged only 110 hours in this particular aircraft, though he had thousands of hours in similar aircraft. Experts say his experience should have adequately prepared him.
sentence2: A daily commuter flight crashed in Buffalo.
