ASN Aircraft accident Douglas C-47B-20-DK (DC-3) C-GSCA Saint Louis-Lambert International Airport, MO (STL)
Very good friend lost his life in this accident - he was with the aircraft when they began fueling - being winter he went inside while they finished refueling.
The refueler who was new - the avgas truck kept stalling on him, so he took it back and got a JetA1 truck to finish refueling.
Nobody noticed the meter readings on the fuel ticket didn't match - before the 3rd take-off - they contacted the FBO to confirm they received avgas - they checked the metered ticket (which didn't add up) and confirmed the avgas truck had been used to refuel the aircraft.
Also had a Aero Commander piston fueled with Jet A1 !!! Fuel was checked and discovered.
