Range of STA (747) ?

There has been mention in this newsgroup of the use of TAL or other
alternate landing sites.

Does an STA-747 have the range to cross the atlantic with some island hopping ?

Say it lands in Morocco or Spain, what would the stopovers be ? I take it
they would choose military airfields in england. Would it have to end up in
a major commercial airport on its way to Florida ?

(think of a the STA pulling up to a gate at a commercial airport with the
shuttle on its top ! Would be quite the view from the gate area :-)

Someone also mentioned the effect of frost on the shuttle which might
damage seals etc.

Since the shuttle is built to survive constant deep freeze and oven-heat
changes, does it really hurt the shuttle to land in a cold weather airport?

And if it does, wouldn't it rule out a TAL site since the STA would then
have to fly via iceland/greenland/newfoundland/new england before getting
south enough to no longer worry about frost ?
