This is one carried over from the old forum
Early this year I dived a Seaeye Falcon to 288 feet on a truck that went through the ice on a lake with its driver. (Minus 43 degrees celsius, -47 with wind chill)
The Falcon opened both truck doors (and I flew it into the cab and set it on the seat to look under the dash) in less than 15 minutes.
Subsequently attached a 1.5 inch recovery hawser to a stanchion on the truck for recovery and brought the drivers body back to surface.
This was with a single function manipulator.
