MY reading of this is completely different (of course !!).
For a start; I am amazed that this is regarded as something that should only be practiced 'by accident' - I would expect this to be part of their normal skill set, it's a perfectly 'normal' set of skills in many of the world's real environments...
To only attempt to do this, unpractised, in times of crisis, by inexperienced folk 'being heroic' is at best foolhardy.
I WANT 'our chaps' to be able to emerge from the merk, unexpected, in 'impossible conditions' at the front door of 'the baddies', and give them a bloody nose... when required.
I am pretty surprised that DB regards this as something of a luck issue - this can be done employing 'normal' higher level flying skills - they should be part of the armory of this kind of operator. It is irresponsible for this to NOT be part of their operating capability.
embarassing to be 'caught on camera' ... but t'will from time to time occur
I do hope these guys don't get a bolloxing... they need to be capable of this, I would be appauled if they were NOT doing this.
