Apparently the small dot I'm looking at heading east towards Dover is an Aramco Beech 350 which has crossed the pond via a stop at Shannon.
The E-4 left Mildenhall late last night after AF1 stopped in for a gas 'n' go. The E4 as Grimm 99 came south over West London efore heading west towards Lands End but the hazy sky and trees at back of garden made even spotting nav lights impossible!
