- 4 - This consisted of fragmented bits of upholstery, soundproofing material, cabin linings, scat cushions and backs, metallic parts of seats attached to and buoyed by these cushions and backs, overhead racks and other light items not essential to the structural integrity of the aircraft. This material totaled possibly less than one percent of all such material within the fuselage. Some small quantity of clothing and other personal effects and several mail bags were also found. The personal effects consisted of shoes, clothing, parts of leather suitcases and other traveling paraphernalia.

Post-mortem examinations of the nine bodies, all of which were identified by fingerprints, indicated that all had received traumatic injuries. There injuries indicated that all nine persons had been seated at the time the aircraft struck the water. No seat belt abrasions were found. The inertia of the bodies was plainly downward and forward and the forces at impact were severe. None of these nine persons had been subjected to fire or smoke before death, as demonstrated by low carboxyhemoglobin levels in blood and tissue. Some of the bodies showed distinct evidence of burning on portions exposed above their waterlines.

A considerable amount of the floating debris also exhibited signs of burning but only above waterlines. Examination of the liferafts and lifevests indicated that they had not been used for their intended purposes or prepared for such use, and all damage had been accidental and random.

Witnesses

A careful search was made for witnesses. Fishermen in the Gulf who were questioned stated that they saw low-flying aircraft, but examination of their testimony indicated that they saw search aircraft shortly after the disaster and not the aircraft involved.

However, at Pilottown, Louisiana, the United States Coast Guard maintains a manned lookout tower for observing surface craft approaching and departing the port of New Orleans. The tower is about 30 miles west of the crash site. The Coastguardsman on duty saw an unusual light in the sky at an angle which he estimated as about 15 degrees above the horizontal and in the general direction of where N 4891C was lost and at about the time it was lost. He did not log the incident. His testimony indicates that the light was red or dark red, appearing suddenly, lasting a "couple of seconds," and then producing a vertical, white light which fell with a white trail. He estimates that the white trail took three or four seconds to go "straight down," and that the initial red flash was "almost as big as the sun." He heard no noise. At the time of these observations the stars were visible, the weather was hazy and there were no surface craft within his range of vision. Subsequent investigation has failed to reveal the use of any marine signal flash or pyrotechnic, which might have had a somewhat similar appearance, at the time and place.

Weather

Investigation disclosed no significant weather condition in the form of fronts, squall lines, thunderstorms, turbulence or icing affecting the route of flight.

The freezing level along the route was at about 14,000 feet and the winds at that altitude were generally from the northwest at 10-20 knots. Except for
