This past Thursday I was driving myself to Terminal C at IAH
and I saw parked on the tarmac to my right of Terminal D an AA
widebody (either a 767 or A300) with a portable stairwell leafding from the main cabin door to the tarmac. Didn't know whether it was an emergency landing, random maintenance, or what. Couldn't find anything in the forum or in the Chronicle. Anybody know what the deal was? Thanks.
