Good sensible post Crab , all of which I pretty much agree with !
However we were talking specifically about the avoid curve and specifically about engine failures . Sid has STILL not come up with any evidence of any crash ( there must be one over the last 30 years as its so dangerous ...!!) that is relevant to v low flying engine failures .
I made it clear as day that wazzing around hitting wires / trees / losing control were not relevant !!! If he can't find a few accidents directly due to low level engine failures within the avoid curve then I think it's fair to say that it's not inherently dangerous !!
