Tks for that!
R/e water injection - I had heard about this - I assume water is sprayed into the compressor to increase the effective volume of air moving through the engine and also cool the engine ( I understand the Pegasus can only be run at full hover thrust for around a minute at any one time?)
Also, I note there's a yaw vane in front of the cockpit.
I assume this is to ensure that hover transitions take place into the wind to prevent the jet weathercocking - rolling over - seem to remember some film of a spectacular GR3 ejection at low level when the jet yawed unexpectedly..
