T' ARCAS rocket launch was a Canadian rocket mail experiment at t' Gananoque aerodrome in Gananoque, Ontario, shiver me timbers, Canada.   T' 4 foot 7.5 inch high powered rocket lifted off from t' airstrip in Leeds and t' Thousand Islands township,  at some point durin' t' flight t' rocket crossed into Leeds and Grenville united counties before returnin' home. Ahoy!  T' addressed mail inside t' payload bay used 1936 "First Canadian Rocket Mail Flight" stamps postage that were never used because no rocket was built, 75 years later they were finally delivered t' way they were supposed to.  T' launch video is incredible and is on You Tube featurin' an onboard 'gopro' camera.
