Raining meatballs. Yup! How many heli pilots look up before starting engines/engaging rotors or hover taxiing? or indeed park their vehicle in the middle of a busy runway or noise sensitive area. Come on chaps, dispense with the ego and think. Before any considerate, professionally minded heli pilots have a go at me. I would agree that sadly a few numb nutss' let you down. Fixed wing guys are not exempt from being numb nuts either. All I can say is, do the best you can to be aware (spacially) of what is going on around you. If you try your best to "build up the big picture" and "notice understand and think about potential rolling goat shags" then you'll earn respect!!
From me too!!
