On some aircraft the issue with manual gear extension is that you have only one shot to do it. If you deploy the alternate system with the gear up, it will not go down. This can make a situation go from requiring a simple fix of the landing gear system to a very expensive gear-up landing.

A good landing is one where everyone can walk away from, a great landing is one where you can fly the plane again. ^
