I note that the Jon Ostrower account states that the aircraft arrived in SFO, did a two and a half hour turnaround and then departed to ORD. I have not read the MM for a triple but I would have thought that a 2.7g positive would have required more than a 2.5 hour inspection.
Reminds me of the cartoon of a ground engineer climbing over a farm fence into a field in which two pilots sit amongst a yard sale of smoking aircraft parts and shouts to them, "Don't put it in the book, it's due out in an hour"
