We had a long weekend this past weekend, so I went to Beirut with a couple of friends, which was really fun. But our flight path was so fascinating, since we couldn't fly over Israel, Palestine or Damascus, we had to take this crazy curvy route. This brought up so many interesting questions for me (How much more fuel did we use? Was this the optimal path? How do you define optimal when human craziness makes the straight line path unusable?).
