I second the previous post about kitty hawk.
The 737's are replacing the 727. From what I hear the new aircraft could not have come at a better time with the high price of fuel.
The majority of those on furlough are now on the street for almost five years. At the five year mark they will no longer be considered as being on furlough. thankfully most of this 5 year group were furloughed before 9/11 and managed to get jobs at other companies so I doubt they will be coming back anyway.
I hope this helps.
