I was attempting to get from Brussels to Minneapolis on that day. I arrived at the airport about 3 minutes (judging by the text I sent to my wife) after the blast amidst quite a bit of confusion (drop-off traffic wasn't moving; me and some others left our rides and walked the rest of the way). I knew something was wrong, but not to what extent. The guy at the information booth at the taxi level told me "it might be difficult" to get to check-in, but I could go in and up one level and give it a try. So I did. Then I quickly turned around and walked back out.
Man, that's crazy. Glad you are alright.
