I happen to be in Houston at the mo and in fact was right in the middle of IAH when the incident became known a bit after 17:00 local. I have to say I was rather impressed by the level of response not only by the airport fire crews but also the city and area brigades. Local media, of course, verged on hysteria.
Landing was eventually shifted from 09 to 15. Flight crew did a cracking job. Just another landing, if one overlooked all the apparatus standing by. Well done.
