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? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
Yep, something failed. Military pilots rack up thousands of hours and don't do stuff like that out of negligence or incompetence. That gif was the easy part - rotorcraft usually tear themselves (and their crews) to shreds when they die.
It is a phenomena that happens with helicopters called settling with power, a.k.a. vortex ring state. It happens with less than 10 knots of airspeed and a decent rate of more than 300 fps causing loss of lift.
The rotor tip vortices get trapped under the rotor and 'burble' up the air and reduces the smooth air flow over the blades reducing lift. The pilot perceives a faster than normal sink rate and adds collective (and power) which makes the vortices worse. Hence the name settling with power.
Mondays are like that.
ReplyDeleteI hope there were no injuries. I reckon the pilot forfeited his flight status.
ReplyDeleteI thought the landing protocol was the ship was suppose to turn into the wind and the helo was to approach from the rear.
ReplyDeleteYes, that's the normal way.

ReplyDeleteEverything that happens after the loss of tail rotor is ugly.

ReplyDeleteoops, 300fpm (feet per minute)
DeleteWell, learn something new everyday!
