I have a mate that did some of the delivery flights way back in 1960 something. Canada to Viet Nam straight over the top of the world. He tells me that anything is warmer than a Caribou when the compass shows south in every direction but those flights are still amongst his most treasured memories. Amazing flying and amazing scenery.
One of my own highlights was as freight on a bou flying over WW II crash sites in the Northern Teritory with a photographer from the National War Memorial. We would come come to a complete stop over the site to be photographed then the pilot would put the aircraft into a 90 degree vertical climb at about 20 feet per minute while the man took his pics. Ok maybe I exagerate a little but that's what it felt like hanging off the ramp. I would never have believed that low and slow could deliver that much of an adrenilan rush. Absolutely the best ride in over 30 years of aviation. They are an iconic aircraft and deserve every word of their legend status.
