Not always true though. There was a recent incident where a diver missed 67 minutes of stops after a 61 metre dive after an uncontrolled ascent and no stops completed. Only symptoms were a tingling arm and messy underpants!

Not quite true. Making headway into wind is to increase airflow over the rotors creating lift which means that less power is required when hovering. There is little downdraft once you're under the rotor disc. A stationary lift can be completed, but it depends on the all up weight of the aircraft and whether or not they have to go away a bit and dump fuel to light the aircarft
