If you find yourself in a situation requiring signaling an aircraft, make sure you use the correct hand and arm signals and dont accidentally wave off the craft by signaling "All OK" like Carl McCunn did.

"An Alaska State Trooper flew over the lake in late August and observed McCunn's campsite. The pilot did not sense McCunn was in distress, since he waved his orange sleeping bag very casually and, on his third pass of the campsite, he saw McCunn casually walking back to his tent. The State Trooper later testified he saw no reason to surmise McCunn needed any assistance.[1][4]
McCunn later wrote in his diary: "I recall raising my right hand, shoulder high and shaking my fist on the plane's second pass. It was a little cheer – like when your team scored a touchdown or something. Turns out that's the signal for 'ALL O.K. – DO NOT WAIT!' It's certainly my fault I'm here now! "
