moggie,
The term Pinch Hitter is from Baseball.
pinch-hit
intr.v. pinch-·hit, pinch-·hit·ting, pinch-·hits
1. Baseball. To bat in place of a player scheduled to bat, especially when a hit is badly needed.
2. Informal. To substitute for another in a time of need.
I think it fits perfectly.
Happy and Safe Flying,
Capt. Richard J. Gentil, Pres.
