That depends. If we manage to move on to a next generation aircraft without getting into a conflict where it's needed then it can be seen as a success. You were able to do a massive amount of R&D and push the state of the art without the consequences of not having gotten it quite right and apply those lessons learned to the next generation. If we get into a conflict where it's needed and fails to meet the operational requirements than it's a failure. Only time will tell.
