Houston, we have a problem

I have to admit I had to go way out of my way to find Level 3 at Houston International Airport. Fortunately, courtesy of my 7 hour layover, I was able to do a thorough search and find the elusive sign. The cameo was taken at the elevator leading to the train depot for gates D and E. This blatant disregard for the time-honored tradition of prominently displaying Level 3 was a welcome distraction in an otherwise long day. I must say, however, the Apollo 13 crew got it right when they uttered the memorable words (which I echo in the tagline for this entry).
