EasyJet claims it has a miraculous new volcanic ash detector

Airplanes never fall out of the skies short of catostraphic
damage...

Even over the Atlantic, they can glide. Mighty expensive glider, but
they can glide and it may be a splashdown but they can land.

But the "zero" threshold for risk in aviation does not exist.
My advice would be to simply stay away from airplanes and aviation
altogether. The sum of your posts proves without contest that you are
terrified of airplanes and flying. That's OK. Take boats, and leave the flying
to pilots.

Safety is a pretty justifiable cause. Nobody dies from accidents until the
accidents occur. The fact that nobody has died from a particular type of
accident does not mean that no precautions to prevent it should be taken.

Flights encountering volcanic ash have been few in number thus far, and
they've all been lucky. Assuming that aircraft flying over the ocean will
always be able to glide to land after an ash encounter is irresponsible.

The current known safe threshold for ash in jet engines is zero.

No memory problem here - that was one of the anecdotal encounters I referred
to. Do you want me to point out the other one, or should I leave you the
satisfaction of "informing" a group of already informed contributors? My point
was that these encounters do not, in fact, in any way justify the summary,
knee-jerk reaction of the Eurpoean authorities in the latest case.

The good side of this is that the authorities' response was so egregiously
inappropriate and disproportioned, that it shed light on the limitations of a
"Precautions Without Borders" policy and most people understood that we are at
the threshold where our precautions are going to start costing lives, possibly
in greater number than the risk they're meant to thwart.

Can we make it a crime to twist words so as to create a clever
acronym?


People get paid money to come up with Characters Rearranged Avoiding
Pertinence like that.

How about PIF trauma?
Western governments are now completely regimented by Pie In the Face stress
disorder.
While a small majority of people still recognize they cannot blame their
governments for natural disasters (notwithstanding attempts at same by
inventing global warming), it has become routine and automatic to blame
them for not reacting adequately and not practicing enough prevention.

Short memory? - check this incident out (I think it's one of the major
incidents that's led to the closure of airways - they don't want a
repeat!) ...

A 747, all four engines stopped, for about 12 minutes.

Not sure why you refer to said encounter as anecdotal. To suggest that
implies the evidence is just heresay, or a) it wasn't volcanic ash, or
b) volcanic ash does not cause problems in jet engines.

Nor do I agree with you that the authorities action is a knee-jerk one.
They go by the data they have - and their recommended closure spaces are
not excessive IMO.

Do you think the authorities *want* to close airspace? Do you think
they do not realise how much revenue is lost to the airline industry and
to countries? (I'm sure they don't take that into account in their
scientifiy analysis - I sure hope they don't - that's not their job.)
