OK, I give up, I have searched searched trying to find an answer and I'm  hoping someone out there can help me.


I flew my AA 777-200 from Honolulu to Kai Tak, which is about a 13 flight.
after I landed I taxied to Gate #2 and I noticed vapor coming out from
under the plane. I think I have seen the same thing in flight, but I have never seen it parked at the gate. I have flown the same flight with the same plane trying to duplicate the effect, but haven't been able to.

Has anyone out there experienced the same effect? I would love to know how it happens, looks pretty realistic parked at the gate.
