Niagara Falls from the air

There are some good youtube videos showing Niagara Falls from the air.

This one is some guy taking photos from a DC 3 - the editing is clever as he put the still of some of his shots in as flash frames.

This is a nice short one from one of the helicopter flights over Niagara Falls, vies some good shots right over the American and Horseshoe waterfalls

The last one is shot on a dull day but still has some good overhead views
