   No I don't think that doing powered landing on the Moon provides a way   
   to get approval to do powered landings on Earth. Even if you perform a   
   zillion Moon landings, you haven't shown that you can do an Earth landing.

   That Y would be zero. Except in some very special cases, if you have   
   even a single failure during the test program, you have to correct the   
   design and redo your X successful landings.
