In July 1972, Al-Gashey was one of several young Black September members recruited for what he referred to as "special training", without having any idea what their target might be. He flew to Munich at the end of August 1972, staying in a hotel and even attending a few Olympic events. On the night of 4 September, Al-Gashey met for dinner with the other members of the strike team, along with a senior Black September operative (believed to be
Abu Daoud), who briefed them on their upcoming mission and drove with them in taxis to the Olympic Village. Al-Gashey claims that until that dinner meeting, he had no clue that the team's target was to be the
Israeli Olympians. Although charged with multiple crimes related to the massacre, Al-Gashey and his surviving compatriots never stood trial. Nearly eight weeks after the massacre, on 29 October,
Lufthansa Flight 615 was hijacked by two Black September members, who demanded the release of the three Munich survivors. The jailed
fedayeen were subsequently released by the
West German government. When they landed in Libya, they were interviewed, with footage of this press conference being shown in the film
One Day in September. Jamal Al-Gashey can be seen seated in the middle of the three, between his cousin
Adnan (believed to be the guerilla who shot and killed five of the hostages who were tied up in one of the helicopters) and
Mohammed Safady. When asked directly if he had killed any of the Israelis, Adnan Al-Gashey simply replied, "It's not important for me to say if I killed Israeli (sic) or not." ==Later life==
