Good input! This is very well received. As I said, the first step is to get a large enough list to get started, get the list approved, then be able to ship samples for testing.

How about any other different sizes? The 15mm will probably be removed. It just does not have too many good uses.

About the port burning C engines, we did have a 3/4C19 that was reliable in testing, but the full C was too much to drill. Maybe if it was done in two operations... In any case, it would be closer to a C32 with the same .3 second burn. Peak thrust of 60 N - 13 pounds. That looks like too much warranty work! >400G's in a Sky Hook!
