AAR can sometimes be problematic. In the following clip, the Italian AMX misses the first time, drops back and re-establishes the correct waiting position. On the second approach to contact, the hose suddenly jerks forward and the brake is applied. Instead of immediately putting on the red light and ordering the receiver to discontinue the approach, the refuelling operator watches helplessly as the receiver makes contact against a hard hose. This cause a whip and the drogue becomes detached:
Steel wire from the damaged hose cause serious damage to the canopy and front fuselage of the AMX; if I recall correctly cabin pressure was lost and the pilot only just made it to the abort aerodrome.
