Regarding a goose hitting MRBs and being a catastrophe, heres my story...
the pilot of an AS350 was setting seismic bags. Noticed something catch his eye. Glanced up to see a ruffled grouse on short final for his rotor disk.
uneventful return to staging area where the carcass was removed from the cooling air inlet and some stringy gut materials peeled off the roof and trans cowl. Some morbid streaks on the blades worthy of a B rated horror flick.
back to drones...
if this fisherman wasnt critical, there was no rush to pick him up. Why fly with the potential hazard if that was the case?
