Had the dubious privilege of being the first Bristow pilot from the Duri/Kotapinang operation in Sumatra to experience an engine failure during flight in a B206, (PK-HBC), in December 1968.
Certainly found plenty of energy in the blades, had got very lucky as I had an open space to go for rather than the usual 150'-200' trees and needed to pull a bit to clear the last line of trees but RPM returned almost immediately when I dumped the lever.
Seem to remember the IAS was about 50kts in descent, flared off at the bottom, big tug on the collective when the grass became obviously grass and cushion on - only problem was that the grass was 5' elephant grass and there was three foot of water! A bit of damage but it flew again a month later when the spares arrived.
Certainly would never have considered a vertical descent in the hope of recovering it all at the bottom!
