Among the 87 fatalities were Polish singer Anna Jantar, American ethnomusicologist Alan P. Merriam, six Polish students returning home from an AIESEC conference in New York, and a contingent of the U.S. amateur boxing team (who were scheduled for a series of exhibition fights in Europe instead of the boycotted Summer Olympics.) According to the doctors who arrived at the scene, many of the passengers were apparently asleep when the plane hit the ground, but some of them – including many of the boxers – were supposedly aware that they were about to crash, as they held to their seats so strongly that on impact, the muscles and tendons in their arms became severed. Some reports suggested that some of the boxers actually survived the crash and drowned in the moat, but no evidence for this was presented. A total of 22 U.S. boxers, trainers, and doctors died in the accident (including the 1979 Pan American Games winner light welterweight Lemuel Steeples). A number of Olympic team members were not present due to various pugilistic injuries sustained before the flight or for other reasons, which prevented their participation in the scheduled event, so they stayed in the United States and survived. Two of the boxers scheduled to fly on Flight 7, Bobby Czyz and Tony Tucker, later became world champions.
