Indeed, but the Comet store has sat there for how many years, to be joint-cased by umpteen gangs of East European "businessmen"
And flogging flat screen TVs from the back of a white van is old hat. I work near a petrol station and have been offered all kinds of stuff when I park my car. Shamefully, one mob offering me TVs spoke my language (Czech) but I didn't reply
Your plane sat there for how long?
It's highly likely it was an inside job, whereby somebody routinely present at the airfield has/had an "assignment" to report planes which are known to be fuelled up and which can be pumped out. It would make no sense at all to have 3 barrels and a trailer sitting somewhere, and watch the airfield from a distance...
I hope you have reported it to The Plod
If they have half a brain, they can set things up....
