HotDog -
All I know is what I read from the posts above mine. That's why I said it must have been brake failure - probably with a severly sloping ramp.
I would never say that an ATPL holder ("although others might say it") would EVER begin to taxi without clearing the right-of-way.
However -
M.Mouse, I believe, implies that that might have happened more than once in the past. Hard to imagine though, the ATPL profession being so "professional" and all.
Could it have been the BIG WATCH obscuring the PIC's view??
Checklists, checklists - what checklist? What - me worry? Nah.
Yea though I ride through the Valley of Death, I shall fear naught, for I am the meanest rooten-tooten sun-of-a-gun on this planet. (paraphrasing the well known quote).
It had to be brake failure!!
