. After breaking off that approach, the crew made a third attempt, but the aircraft was too high to land safely. After assessing the weather and fuel situation, the crew elected to divert to St. Croix, and received a vector and clearance. At this point, the crew noticed a possible discrepancy between the fuel gauges and what had been computed as the amount of fuel remaining. The captain advised ATC of his intention to ditch the aircraft, and began a low approach over the water. Flight 980 ditched in the

was not working on the plane, so the cabin were not given any warning of the impending ditching. Consequently, an unknown number of passengers and crew were either standing up, or had their seat belts unfastened, when the aircraft struck the water. The sea was rough at the time as a result of the weather conditions. The aircraft remained relatively intact after the water landing, but soon sank in about of water, and was never recovered. The accident resulted in 23 fatalities, as well as injuries to 37 of the 40 survivors. Both pilots and the navigator survived. The survivors were left bobbing in the turbulent and shark-infested sea in their life jackets until rescue came. Recovery of the survivors by helicopter began approximately hours after the ditching, and the last survivor, the first officer, was picked up about 1 hour later.

(NTSB). The report concluded that the cause of the accident was poor fuel management, complicated by the crew's inattention and distraction as a result of the weather situation and multiple diversions. Some specific issues cited include miscalculation of the rate of fuel consumption, misreading fuel gauges, and incorrect computation of the amount of fuel expected to be remaining at the time of landing. The NTSB report stated: The NTSB also concluded that the chances of survival in the accident were worsened by poor coordination among the crew before and during the ditching. The recommendations in the report included adding "warn passengers" to the checklist of procedures for emergency landings and ditchings, requiring that flights not be dispatched without a working
