The points are well made, although clearly if you accept too high a risk of losing the aircraft and personnel, then you are almost certainly accepting a similar risk of programme failure - since without them, you really are up a polluted creek without a paddle!
Wyvern and I have offered a paper to the symposium; we don't yet know if it's been accepted, and it's not exactly what you are describing, but I think it might go a fair way to accepting your challenge Teadriver; perhaps somebody would like to pass judgement after the seminar!
If you check your PM's, I'll send you the abstract.
