Evidence?
I don't have any evidence except we have been able to circumnavigate this things forever in Asia and Alaska. What is the Met offices evidence that something bad will happen if we do fly through the area? And if they do have evidence why would they let a BA flight go through it. (paperwork will not make the difference by the way).
It is an abundance of caution that wreaks havoc upon the masses.
The government could't be wrong. Right???
