Geese hatchlings imprint on avid bird enthusiast Christian Moullec. He cared for them every day and trained them to accept his piloted microlight as part of the family, so that when they all took to the skies, he was able to film the imprinted flock flying in tight formation. EARTHFLIGHT: Flying High, which looks at the making-of the EARTHFLIGHT series, airs Wednesday, October 9 at 8PM ET (check local listings). (Restricted to U.S. and Territories.)
