Wow, great story!
Thanks for serving my country... even if I wasn't alive at that time.
Anyhow, yeah, Love Field is my favorite airport, and the globe is still there.
They've recently redone the flooring in the baggage claim and rental car area, and I was afraid that they'd redo the lobby floor as well (you can't exactly say that the inlay is up-to-date; the borders have changed countless times, the iron curtain has fallen, and many of the countries on it no longer exist) but it's still very cool.
But yeah, as of May 2007 it was intact.
The rest of the lobby is a let down, though- the observation deck has been gone for about 20 years, and the restaurants are long gone, too.
