i have heard of a case where the rescue heli landed on a beach, crewman got out, walked around to 4 kids that they were trying to rescue, then the helicopter went around and winched all 5 of them back onboard....
If the crewman could walk there, why couldn't the kids walk out?
That report came from the parents of 3 of the kids, and they were wondering why the kids couldn't walk around to the helicopter.....
