In addition to controlling Germany's border, the BPOL serves as a federal reserve force to deal with major disturbances and other emergencies beyond the scope of Land police. The BPOL guards airports and foreign embassies, and several highly trained detachments are available for special crisis situations requiring demolition equipment, helicopters, or combat vehicles. After shortcomings in police procedures and training were revealed by the terrorist attack on Israeli athletes at the 1972 Olympics, a task force known as Border Guard Group 9 (GSG-9) was formed to deal with terrorist incidents, especially hostage situations. The GSG-9 won world attention when it rescued 86 passengers on a Lufthansa airliner hijacked to Mogadishu, Somalia, in 1977.
