A few years ago, I was sent a similar question like yours by a guy I knew...
Turned out his company asked him to long line a generator, without him having done long line ever before.
Company told him it would be "just like sling load, no problem", and that they would send an experienced long line pilot who had no experience on that type to assist him.
Turned out this guy had not done long line either.
Despite all my warnings, the company pushed them to do it.
The load came off the ground, and as the aircraft gained speed, they shifted their attention from vr to inside... Dropped in altitude, generator hooked onto a tree, and they crashed into the ground, leaving a 10m hole on the ground after Impact at more than 200 km per hour.
So if my reply ***** you off-I don't care 2 CT about it.
In this business you need to learn from other people mistakes.... Because you won't live long enough to make them all yourself.
