And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two?

ground resonance. one corner touched down early. it happens so fast that the bird disassembles itself before the pilot recognizes it. the cure is to lift off again, but your reflexes are rarely fast enough.
Ground resonance. Up on collective, quickly. And you have to happen to be spooled up enough to have power to get off the ground. Helicopters with aircraft style landing gear with struts and tires are much more susceptible. If it starts to happen and you're onboard get as close the centerline of the rotor as you can and hang on. Everything will be flying away from you.

ReplyDeleteEvery time I was on an army chopper it felt like it was gonna fly apart. Overwhelming vibration.
ReplyDeleteI had a drag boat break a prop blade at a 100+ & the power head came apart like that. Every experience.

ReplyDeleteAny landing you can walk away from is a good landing. Especially from a Soviet design.
ReplyDeleteI've heard the Jesus nut can do that.
ReplyDeleteMust been a few hairy moments.
