Written off Saint Louis-Lambert International 9 Jan 84. From the ASN report: The first two attempts to takeoff were abandoned due to slow aircraft performance. Takeoff was continued on the third attempt, but both engines lost power upon gear retraction. An attempt was made to make an emergency landing on a highway, but the left wing struck a pole. The aircraft crashed through a fence and struck a highway embankment. PROBABLE CAUSE: Jet-A fuel had been used when refueling the aircraft, instead of 100LL Avgas.
