Hello,
Here is a link to a video of a R22 attempting to bomb my M3A1 Stuart tank with a 5lb. bags of flour! I was inspired by the 1941 Laurel & Hardy movie Great Guns!!! Although it appears the helicopter scored a hit there was no flour on the rear of the tank. So...USA 3...the Axis Powers 0!!! This was at Heiser Farms in Dayton, OR.
