Realizing that the Palestinians and Israelis had to walk 200 metres through the underground garages to reach the helicopters, the West German police saw another opportunity to ambush the perpetrators, and placed sharpshooters there. But "Issa" insisted on checking the route first. He and some other Palestinians walked pointing their AK-47s at Schreiber, Tröger and Genscher. At that time, the police snipers were lying behind cars in the sidestreets, and when they approached the latter crawled away, making noise in the process. Thus the terrorists were immediately alerted of the dangerous presence, and they decided to use a bus instead of walking. The bus arrived at 10:00 pm and drove the contingent to the helicopters. "Issa" checked them with a flashlight before boarding in groups.Interview with Tröger in One Day in September
