as a helitack crew supervisor (retired), I have ,along with crew, been taken off hill tops and had low drops that spread the fire. and most of those pilots were the best of the best. shit happens. you just recover and move on but you do not ground the aircraft or pilot for a bad drop. the pilots out there will vouch that the air that all these pilots have to deal with is usually at the edge of the envelope along with the turf the also have to deal with. one bad drop does not mean the pilot or aircraft needs to be removed. there is always a learning curve for fighting fire: whether on the ground or in the air. this ship is an positive asset along with the pilot. tread lightly with judgement.
