I'm a helicopter pilot, don't hold it against me!
Nothing wrong with that
Helicopters regularly tow banners in other parts of the world....which always striked me as mad !
I did read an NTSB report of a banner tower in california who picked up the banner and the wire got caught in the rudder causing a full deflection to the right. Still he flew 75% of a circuit and managed to land it on a golf course, which must have given the golfers a bit of a fright!
