Hi,
I've been to San Blas, by boat, not by plane, but I have seen that tiny plane land there. If I recall correctly, it landed on a grass runway, and one that was not too even either. I recall seeing some bumps and ruts. When we saw the pilot take-off, it reminded me of those movies where you see someone steal a plane who does not know how to fly the plane. We saw the plane lurch and dive and lurch up again and tip from side to side as if the pilot were taking his first flight without having had a lesson first. You must have had one heck of a ride.
