The truth about the balls up the Met Office made about the ash:
*Attempts to measure the ash's density were hampered because the main aircraft used by the Meteorological Office for this purpose had been grounded as it was due to be repainted.
* Computers at the Met Office, which earlier forecast a 'barbecue summer' last year and a mild winter for this year, produced a stream of maps predicting the ash would cover a vast area, eventually stretching from Russia to Newfoundland. But across almost all of it, there was virtually no ash at all, and none visible to satellites.
* Though there was some ash over Britain at times during the ban, the maximum density measured by scientists was only about one twentieth of the limit that scientists, the Government, and aircraft and engine manufacturers have now decided is safe.
'We never understood why a blanket ban had been imposed - something that would not have happened in other parts of the world,' a senior airline executive said yesterday.
On April 15, in satellite images, the Icelandic volcano plume is clearly visible as a streak of orange, or 4.0 on the scale. Scientists say that anything more than a 2.0 could indicate ash. The maps make it clear that for most of the shutdown, ash was visible over only small parts of Britain, and on some days, there was none at all
As the days went by without the restrictions being lifted, its clear the policy was based on theoretical models which had little grounding in reality.
The Met Office strikes again..............
