I guess the other relatively nearby airports were also pretty foggy, so we were diverted to Newburgh, near the Hudson River about halfway between here and NYC. (Well, closer to NYC.) Along the way, we learned that the incoming Philly flight to Ithaca was diverted to Rochester, where they put everyone in vans. I'm not sure who got the better deal.
We were met at a pretty dead Newburgh airport (Stewart?) by a skeleton ground crew and a refueling truck, and we were probably on the ground for 20-30 minutes, with the door open for fresh air, though we couldn't get out. At least we could stand up and stretch.
Woo! No waiting in line behind eight other planes to take off again! We flew pretty much straight back to Ithaca and landed. Pretty cloudy and foggy as we came in, but the visibility around the airport was good enough.
We'd boarded at ten and landed at two (instead of 11:35). So, all told, four hours on the propeller plane, too much of that spent circling. Starving. Ate cookies. Bed soon.
