Throw in erroneous attitude information, turbulence and thick cloud and his chances of getting out of that alive would be zero.
stating the obvious, we already know he / they didn't get out alive.
There is no "Devil's Triangle" in that area. That is nothing more than a journalistic dramatic beat up. Nothing is to be gained by re-visiting the search area. Quite the opposite in fact. There would be a real risk to life and limb of those hardy and well meaning volunteers who would willingly spend their time trying to locate long since deeply hidden wreckage in impossible country.
I'd argue it is indeed as relevant as a "Devils Triangle" gets for Australia. Considering the amount of aircraft that have gone down in this region and the difficulty in locating them. It's provided the terrain that has yielded the only missing aircraft on Australian mainland never to be found. I can't really think of a more fitting name for such a location.
There is much relevance to revisiting the search area. Plenty of us have done so and are continuing to. Perhaps ask the families of the missing occupants if they see there is nothing to be gained.
Yes the area is not without it's risk, but much of this can be mitigated with adequate precautions.
Quite surprised you'd take this position Centaurus. If people want to keep looking for it, really, what is the problem?
