Plug for the CHF here. The first helo on scene was a Junglie Sea King who happened to be in Lincolnshire with the yellow helicopters boys arriving about 15 mins later (no disrespect implied). Spartan 2 (GR4) stayed on task for the best part of an hour with Rocket also loitering as 'top cover'.
From looking at the radar, it would appear that Chap took a very well considered turn into the range before jumping out. The feeling we got from our end was that the injuries were nothing more than could be expected after a premeditated ejection.
