Personally i think its about time they replaced the aging shuttles with new
ones; or are they just gonna wait until they have none left!!??

Apparently the shuttles have to be re certified in a few years. The cost
of doing this is huge.

I think the best solution now is to bite the bullet. Change to the
Russian launchers, dump the shuttle and use the money saved on the
shuttle to start immediately on the new launchers.
