It's really strange reading all the comments here regarding some thoughts on the perceived experience of the pilot by watching a video.
Also, can all the firefighting pilots tell me 100% sure that their empty buck never swings? If you say yes, I'll say you are probably dreaming, since you don't watch your bucket 100% of the flying time.
I know the pilot on that video, and I can assure you he is not a rookie. But, then again, probably in some places you don't have the training you should have (talking without prove!), probably pilots should have a better training...
Maybe different zones requires different approach and thinking.
Have in mind the situation, fire close to houses, actually homes of someone. Also, this type of operation is normally coordinated with ground forces, and ground forces are the ones who request the drop (60% of the time).
Also, that camera should never be there, in the tail of the helicopter, that's a fact.
For disclosure, I am not a fire fighting helicopter nor do I have experience on it.
But I know, as a helicopter pilot, that is always easier to spot the bad piloting on others than on ourselves... You became a better helicopter pilot when you know what you do bad and try to correct it.
Cheers and fly safe.
