Yes you did see a lightning. The company who own it are called CastleAir - the same company that flew Annica Rice around England all those years ago.
From what I've heard, they had an immense fuel to noise ratio. Must have been fun though. Small airframe, tiny wings and two erking great donks hurtling you through the sky. Oh for the cold war......
Ive been lucky enough to take a squirrel into there a few years back. Can be tricky with the wind direction and power cables !
(well it felt like it when I was in training)
