-28- Autopsies were performed on five bodies under t5e direction of the Boone County Coroner, and an additional five under contrsct for Air Canada. No evidence of antemortem impact injuries was discovered during these examinations. 1.14 Fire Response Although the fire on board Flight 797 began in flight: no one saw flames in tine cabin until after the flight had landed and tine survivors had iett the airplene. The last passengers to depart the airplane through the left and right overwing emergency exits stated that they saw flames Immediately after stepping onto the wing. The firefighter on scene commander stated that some of his men went to assist the passengers down from the wing and that, at that time, he saw flames in the cabin. The crash-fire-rescue vehicles entered runww? 27L at its approach after Flight 797 landed and followed behind the flight until the airplane was stopped. According to ?he fuel gauge readings noted during the cockpit documentation, the center wing tank was ernpty and there were 6,200 pounds and 6,050 pounds of jet-A fuel In the left and right wing main tanks, respectively. The airplane's fuef tanks did not ruptcre and the jet4 fuel was not involved in the fire. Flight 797 came to a stop about 1920, and 7 airport cresh-fire-rescue vehicles containing 13 airport firefighters were positioneS st the airplane. (See table 1.) Upon arriving et the aLLp:ane, the firemen saw heavy smoke roXiw out of the overwing exIis ' . and front doors. About i921, as suxiuing passengers and crewmembers were departing the airplane, the firefighters initiated an exterior attack on the fire. Foa~ was discharged fro!n the turrets on the firetrucks onto the top c: the airplane's fuselage and Q on the ground beneath it in order to cool the interior of the airplane and to povide e foam blanket in case of a fuel spi!!. Other firefighters assisted pasenzers at the escape s!ides an2 helped passengers off the wing to the ground. %-hen the on scene commander ordered an interior attack on the fire tc be made for rescue purposes and to extir!guish the fire, passenge-s were still letlving the airplane through the left forward cabin door and overwing window exits. The first interior etteck was made through the left aft window for several reasons. According to the on scene commander who executed the order, he believed that most peopie would try io esir the airplane through the !eft forward door; therefore, he did not want to Dlock that exit with a !adder and hose. ALSO, with the escape chute deployed. it would have been difficult for the firefighters to enter at that door with their protective equipment and hoses. The on scene c.>mmander t.estified that it would have been possible, "but it would have s!o*ed us down.'' Tte on scene command-r also testified that he wanted to enter the airplene through the overwing windo~w exits, "because we wanted to get in between the passengers and the fire to make their chances (to escape) bettcr." Within minutes of arriving at the eirplane and aftar the passengers were off of ?he left wing, two firefighters momted the left wing carrying a 1.5-inch handline, opened the left eft overwing emergency exit, and applied foam into the cabin. The firefii;-!?ters were wetiring proximity suits wilt, sc1f-conta;ned brcathing apparatus; however. they were not wearing the proxi!nity suits' protective hoods bccause the hoods did not fit over their brcuthing eppnratus. .Af:er spp1:jing the foam into the cabin, they attexpted to enter it throw$ the overwing exit but were drivel? back by the intensc smoke and ktit. According to one of the firefighters;. he did not see any flames during this a.ttc:np? to enter the Q
