On 28 August 1988 three jets of the Italian aerobatic team Frecce Tricolori collided during an air show at the US air base in Ramstein. Sixty-seven spectators and three pilots died. On the next day, aerobatic displays were banned in Germany. Three years later they were allowed again under safety conditions. One of them is that no maneuvers may be flown over the spectators or toward them. Infusion needles with the Rekord cone, then still common in Germany, were replaced by needles with the internationally standardized Luer cone. A support group for survivors, relatives and rescue workers was set up, the first of its kind in the Federal Republic.
