Pipe is a FedEx guy. Although he probably hasn't flown a 737, he likely knows what he's talking about when he talks about retrofitting old airplanes.

No, that isn't a shot at FedEx. FedEx was one of my top 2 choices when I was putting out aps. Just putting his comment in a perspective that I previously lacked. Plenty of turds being polished as they come online at FedEx.
