This ties in with Mary Schavio and her "a 25 year old aircraft is unsafe" garbage! Just because "Fly By Night Airlines" operates a 25 year old (or older) DC-9-30 (according to "Queen Mary - The Self-Appointed High Priestess of the Airline Industry") it is unsafe because they are a low-cost airline, doesn't mean that the same DC-9-30, operated by Northwest, IS safe because they're a major. That's a load of crap. It sold a lot of books for Ms. Schavio but lacks substance.
Just like old cars, it isn't the age that's on them, its how well they are maintained (and have been maintained in the past).
DAMN! This SUCKS! I just had to go to the next higher age bracket in my profile! :-(
