Weird. I recall when the shuttles first began flying, reading about how the
bottom of at least some the ships (certainly the first) were being examined
for damage remotely, by telescope from the ground. Further, I distinctly
recall reading an article that described, and I believe had one or more
photos of, a tile repair kit for use in space. What happened to all of
these things, I wonder?
I must admit it also seems very strange that the shuttle couldn't have been
examined while docked to the ISS.
By coincidence, a tube train in London (where I live) jumped the track last
week and tore up a station, when one of its traction motors dropped onto the
rails. Thanks to that, the major east-west tube line has been out of
service for days, causing travel chaos. Apparent failure thanks to deferred
maintenance, by way of ill-advised cost cuts -- twice in one week,
seemingly.
