When I said this story was probably urban legend, it's because I did read about it several months ago, perhaps even a year ago in another web site. Either that or it was something very familiar that involved a military funeral escort. This story is very similar to the one about President Clinton ordering a US naval vessel to port in Vietnam with the US flag lowered. Although that, too, was blogged and even reported by a reputable news source, it never happened. And I'm thinking the same about this supposed TSA incident.
But some of you are determined to believe what you want, and that's fine. Until I read a credible source, I'm still going to think this is an urban legend.
