Had a whizz down to Portsmouth to watch the D-Day remembrance fly past. Met up with Flooky for a quick catch up, then headed east to Beachy Head to watch the flight of Dakotas en route to Normandy. The Daks takeoff time from Duxford, was delayed somewhat, which made for quite a wait on an exposed windy hillside. Glad I toughed it out as they were quite a spectacle. Then A22 London bound, rolling on the drive with 222.2 miles exactly, on the clock.
Come on CERI......you know the rules.....
then cross country too Durrington to have a look at a fake stonehenge
