My negative review comes when people show up scaring others out of air travel. I find that all posts like yours do is upset "cautious flyers" and serve no other purpose.
My Grandfather worked for an airline for years. His one quote on safety was that the airline in financial trouble or with the most recent crash was actually the safest. He felt the FAA kept a closer watch on those airlines.
I also want to point out that the site you linked to is not an "Official site". While I have no reason to distrust it, I have learned over the years that sites like that are dependent on people keeping them accurate so I don't use them.
Your expert opinion does not give us any stats to verify the claim that they are unsafe or can't keep thier trucks running. Having spent some time cruising the reference site, I see no comparison stats etc.... You appear to have copied the accident data base for one airline which is very misleading. For example, you Sept 22, 2000 "accident' occured with 0 passengers on board while the plane was in a maintenace as indicated "For the maintenance check, the mechanics had taxied the airplane to a remote taxiway on the airport and had performed three runups for which no anomalies were noted. During the fourth excursion to high power, at around 93 percent N1 rpm, there was a loud explosion followed by a fire under the left wing of the airplane. The mechanics shut down the engines, discharged both fire bottles into the No. 1 engine nacelle, and evacuated the airplane. Although both fire bottles were discharged, the fire continued until it was extinguished by airport fire department personnel. The aircraft was damaged beyond repair."
Seems to me that in that case maintenance was working as I would desire and I would hardly hold that against USAir.
Now, I would not buy a ticket for travel on them this summer, but only because I am concerned about the saftey of my money!
