I don't know if anyone has noticed this or not, but the tail number is 40059, which is a 1984 C-5B model. I mention this because I was listening to Fox News about 08:30 this morning and they had a telephone interview with a retired General who mentioned, when asked about possible causes, that the C-5 entered service in the 1970s. Thereby implying that its age may have something to do with it. Well, OK, but this one did not enter service in the 1970s.
However, to Fox News' credit, I just heard them specifically meniton it was a C-5B.
I remember riding on a new C-5B in the 88-90 time frame; it had only 24 hours flying time. Too bad it's one of the B models - they're a lot newer.
