Really solid work here. The music was catchy and the visuals were surprisingly clear for how complicated the paths were starting to get. I had the thought that this entire game would be resolved by just making a cue and routing appropriately, but then the slow planes reaaaaally throw a wrench in that.
I think I wish the selectable spot for landing a plane was a little larger. I kept accidentally clicking past the runway and into the space in front of the hangar and having to undo. Extremely minor nitpick though.
I got like 80 points, so I hesitate to comment on depth, but I do wonder if more verbs would help extend this game's lifespan a little bit. A quick "do a little spiral" input or some other panic command, maybe?
