Analysis

A Learjet 35 was cleared on to runway 09L and hold, the Learjet crew confirmed with the air traffic control tower personnel that te transmission was intended for them and taxied into position and held. Personnel on duty in the control tower then cleared a Cessna 403 position and hold on runway 13. The tower personnel then cleared the Learjet for departure and he acknowledged. Both aircraft then began to take off and missed each other by about 10 ft after becoming airborne. The pilot of the Cessna stated later that he thoght the clearance was for him.
