Our maintenance is embarrassing. Our Lavs on -300's are held together by duct tape, we defer stuff all the time that might be legal but less than desirable, and are our fuel tankering program is a joke. A dude sitting in a room with no windows in Dallas tells us to land in SNA with an extra 5k in gas because a chart says we will have 1000' of stopping margin at flaps 40 with Max Braking and we do it. Good thing we are turning on the automation in the 300's . . . ooppss.
