Just been buzzed...

[Hard-Drive]

...outskirts of Rugby, Warwickshire. Two fairly meaty prop driven aircraft (about 75% sure piston not turboprop), very fast, heading south (ish), and clearly at or above 500 feet, honest, not.

Any clues? Someone was having fun!

There was a couple of Sbach's buzzing around Northampton, I wonder if it was them?
