I recently finally made it to Abbeville, France in the Lancair Legacy on my around-the-world trip (started in Battlecreek, Michigan), on the way I noticed in Canada, Greenland, Iceland, the UK, and France all AI aircraft have N numbers. N numbers (as in N---- tail numbers) are supposed to be for the US...so what the heck is up with this?!
Normally I fly local or in the US only so I never really noticed this until this trip.
By the way, the airspace in Europe SUCKS!!! so many restrictions, I dont know how you Europeans stay sane with all the controlled airspace and restricted areas! (Here in the states we have plenty of room to play around).
