I recently arrived at JFK from SF. Delta flight, I believe it was terminal 1. Before being released into the general airport we were corralled in groups of about 8 at a time into a clear chamber, told to wait a moment, and then let free. I've never seen anything like it. Like a weird gas chamber. No explanation, and I can't find anything about it online. Anyone know what that was all about? I haven't experienced that at any other airport. Did they spray me with the AIDS?
