First time viewer...
I happened to see this last week for the first time (didn't get to see the entire film because it was on a channel that I didn't know was available - lol), but it convinced me to follow up on learning how to fly a powered hang glider (there's an airport about 60 miles from here that offer lessons - if they're not too expensive)...
I didn't see a message board topic about this, but many might not realize that this is loosely based on a real-life incident:

imprint training is actually nothing new, but it's always impressed me that wild creatures can become that attached to a human that they consider it it's guardian, in a sense...
P.S. My old China Beach friend Dana Delany has a supporting role but comes through in Lt. McMurphy fashion when she yells at the bulldozer operator to "SHUT THAT THING OFF!"
