The MD-82 crew is understood to have uplifted 15,400kg (34,000lb) of fuel to perform charter flight WCW708 from Panama City to Fort de France, Martinique. This was more than sufficient for the planned 2h 38min flight’s planned route, providing an estimated endurance of 4h. The flight left Panama City’s Tocumen airport at 01:00 local time and headed east, intending to fly a course that would take it over northern Colombia and Venezuela near Maracaibo.
The wreckage indicated a high- velocity impact, but heavy rain doused any post-crash fire. Late last week at least one of the flight recorders had been recovered. Panamanian aviation authorities said on 17 August that the fuel source at Tocumen airport from which the aircraft refuelled had been certified uncontaminated.
