I've heard this story 50 times at my field all ready...

This guy was flying his T-Rex, small electric heli mind you, and it went down way off in the distance in the woods and at that second he stuck his arm out pointing straight where it went down and had another guy get his GPS out of his truck, pointed it where his hand was pointed had it set a line straight to where he saw it go down, he followed it and came back out 20 min. later, which is amazing because that was all probably the time walking to the area I was told.

Because he set a line on his GPS, once he got to the area he could wonder around and if he found nothing he could easily go right back to the line of sight where he saw it went down. Genius!
