So how come I saw a plane today??

We were driving between Colchester and Braintree at 4 o clock today when my wife suddenly spotted the familiar jet trail high in the sky....I looked and sure enough, it was a plane at about 35,000 feet......wtf??

Pakistan Airways should be flying as normal...

Here's my answer!

Test flights. Been a few today apparently.

If Lufthansa come over again, the Hurricanes can be scrambled at 20 mins notice.

On the news earlier tonight, if I heard it correctly. some planes can fly but have to be 20,000 feet up, above the ash cloud.
