Where does one find a 5"x7" glass signal mirror?

More to the point, Where does one find a 5"x7" glass signal mirror that
will survive an airplane crash?

I expect that if a person in the airplane survives well enough to use a
5"x7" mirror, that the 5"x7" could be stowed in the airplane in a
sufficiently well-protected spot for it too to survive the crash. Probably
just keeping it away from the sides of the fuselage, and not packed against
hard objects, would be sufficient.

However, sure enough at the web site of the company Jer/ mentions --
http://www.wisesurvival.com/wisesupplies.shtml -- there is only a 3"x5"
mirror. I'm still wondering where one might find any 5"x7" signal mirror,
crashworthy or otherwise.
