Hmmm - there are, as in most things, exceptions. Professional S&R pilot plus three crew, hover-taxying up a valley in the murk, enters IMC and decides to climb out. Good move?? Well, actually no!! Climbed into the base of a Cb and they were spat out of the side at 12,000' ... as a kit of parts! 4 fatals, friends amongst them. Probably the one exception to prove the rule but, sh1t happens ... especially in helos.
