Don't worry Patrick, you're talking about a 4 sensor, daylight launch only, space agency. There are probably backup bolts somewhere.
Talk about redundancy... Watching an interview on NASA TV this evening I learned that the four H2 sensors are themselves part of a backup system that will only be used if something else goes wrong after launch that requires a non-standard climb to orbit. So if there's a normal climb out none of the 4 H2 sensors will ever be used. One has to wonder if maybe one can put too much redundancy in a system. Patrick
