Gibraltar X, trick flight through road tunnel

I was exploring around Aerosoft's Gibraltar X scenery and was having a bit of fun. I made it through the tunnel in the terminal building on my first attempt, flying my BN2 Islander.

I nearly took the roof of that bus that was just entering the tunnel. It's interesting that on the replay, the bus is not there. I really like this scenery package. Another trick I did, was land a helicopter on the ridge, then change it into the Islander and launch the aircraft a bit like a hang glider off the top. It works fine.
