I'll ask the stupid question. If they have to dump fuel anyway, why not proceed to destination?
Been asked already. I do not know why. I suspect - SOP. Pilot declares emergency and procedure is to land at the nearest airport. He surely declared emergency on takeoff.
Anyone else?
If I had to make an emergency landing, IAH would have to be one of the best airports in the world to make it. Also, Houston is the hub from which these jets operate from for Continental Express. All their maintenance facilities are at IAH.
Not a stupid question. I think they want to keep the plane in Houston for investigative reasons. Costs more to fly it forth and back. Also protocols under the cirumstances. Flying with gear and flaps down probably not acceptable cross country. Others who know more will probably cime in.
