re: If you needed a reason not to stand under a sling load

I managed a heli lift a number of years ago on a 26 story building down town BR. Had 2 lifts up and one lift down with some large fans.

Their lift coordinator on the roof with us said he would pick up the first ground lift and set on roof. Then take off the old fan then set new fan in its place. He warned not to get under lift. That in emergency pilot would release his load. First two picks went as planned. On setting the last pick pilot panicked and hit the release. Part of the rigging glanced the hard hat of one of my men. We got lucky.

And as to that lift. That is a Baltimore air coil (BAC) logo on the side of the equipment that was dropped. That is a cooling tower.
