...and how predictable - the safety of people in the air is now being put under pressure by financial forces as the ban extends again. I appreciate how desperate the situation is, but you cannot, and must not allow aircraft full of people to fly through volcanic ash - no matter how much danger the airlines are in of financial ruin, regardless of how many days your family have been stuck in Mallorca. Everyone is desperate to get the planes in the air again, but some are advocating playing games with peoples' lives in order to get there.
It doesn't matter if the airlines do go bust, it doesn't matter if you end up having to cycle back from Turin - as undesirable as both scenarios are, they are infinitely preferable to the possibility of a single airliner dropping out of the sky with engine failure. Not just for the obvious loss of life reason, but also for the defence of the principle of 'safety first'. If we allow a fudge that permits an "acceptable level of risk" under commercial, governmental and popular pressure, - that sets a precedent that when the **** hits the fan (no pun intended !), it's ok to start bending the rules - and this is one industry where that cannot be permitted - under any circumstances. History is littered with disasters caused by safety being impinged by commercial pressures, and it's concerning me greatly that we could be watching another one unfold before us now.
The bottom line here is that almost everyone calling for the ban to be lifted isn't qualified to make the scientific and engineering judgements on what is safe and what isn't. They are arguing their corner from a commercial / financial or personal perspective - and that includes most people on here too.
