How much of a safety factor were the space shuttles' wings designed to withstand on a re-entry?

Manrating standard is 1.4 FS. However, reentry may not be the design case, it is more likely Max q during ascent or buffeting by winds during the landing phase.

Thanks for the reply Jim. Someone asked me if the shuttle could re-enter from the moon? I am one who is known to readily engage in armchair aerodynamics. I had to say "I'm not sure."

While I know it's impossible for the shuttle to get there in the first place, why worry about a re-entry?

But the question still haunts me; If the trajectory were shallow enough and the heat pulse planned over a long enough time, would the wings take the loading?

Wouldn't it also depend on which orbiter? Weren't the wings of Columbia (and Enterprise) made of different materials than Discovery and Atlantis (and presumably Endeavour?)

The issue is TPS and not structural, I believe the dynamic pressure isn't that high.

Well if you can put the orbiter around the moon certainly you can put it back into LEO for a normal reentry. You would have to get it into LEO to allow for weather issues at the various landing facilities.
