The ash cloud that never was: Inaccurate Met Office forecast causes airport chaos for 50,000 | Mail Online
A CAA spokesman said: ‘The Met Office model was predicting ash which was not there when the test
flights were done. We have asked the Met Office why their forecast model showed something which
was not subsequently backed up.’
Not entirely sure why the CAA regard an inaccurate Met Office
forecast as something out of the ordinary, but...
The second concern is that clearly if ash is
not present where the forecast says it
is, it may also actually be present where the forecast says it's not. I hope that at the pointy end, the presence of white on the charts is not being substituted for the mk1 eyeball and see and avoid.
