Note to Osprey Pilots: down drafts are dangerous

During a NY air show, an Osprey tilt rotor's downdraft caused branches to break off of a tree with spectators under it.
Several people were injured.
The Osprey was skimming the treetops to show it's handling capabilities.
It is a bad deal when people are injured at these shows, especially when it is obvious in hindsight that the flightpath should have been cleared and the tree was not very strong.
