These poor devils needed a boost.

I never saw a Mi-26 struggle like this:

This is aviation's equivalent of the bridge scene in Sorcerer

Perhaps a chopper atop RATO units could fly in--rescue hostages--boost up then drop the rockets.

Somehow, I think somebody used way too much vivarin when they should have been sleeping.
 
In the UK Saro tested what appears to be an identical system on a Skeeter . . .

'When G-AMTZ had received its new engine, it had been redesignated the Skeeter 6. After gaining its C of A with the Gipsy Major, it was modifed yet again in May 1957 by the addition of a Napier NRE.19 High Test Peroxide rocket booster system to the main rotor. Propulsive nozzles were fitted at the tips of the three blades, fed by an HTP tank mountedbove the rotor hub, providing 67 eshp and increasing vertical climb rate considerably. Endurance was a little under 15 min, and the system was designed to give the Skeeter tropical performance as an alternative to the de Havilland turbo-supercharger also being considered. Only G-AMTZ and Skeeter 6 G-ANMI were modified in this way despite the obvious
advantages; the HTP-boosted Skeeter was deemed unsuitable for military use because of logistic considerations.'

Was this an independent effort, or was there any 'cross-pollination' ?
