Concerning the seeming inability of NASA to resolve the fuel
leak problems:

I don't recall NASA having these problems earlier in the shuttle
program (i.e., STS 1 - 25). Is this all a recent phenomena, or
did they have leaks before, but the mission scrub threshold was
higher so they flew anyways? Or are they now performing more
leak measurements and are finding leaks than might have escaped
detection before? In other words, is NASA being more careful
with respect to leaks in the post-Challenger era - or is this
a hardware problem unique to these missions?

Henry - what do you think?
