Aside: this may interest some of you.

I have a first edition of Charles Lindbergh's "The Spirit of St. Louis" (1953) in my library. The appendix is particularly interesting, including this:

Emergency Equipment Carried in the Spirit of St. Louis on the flights between San Diego and Paris

1 air raft, with pump and repair kit
1 canteen of water -- 4 quarts
1 Armbrust cup
5 cans of Army emergency rations
1 hunting knife
1 ball of cord
1 ball of string
1 large needle
1 flashlight
4 red flares, sealed in rubber tubes
1 match safe with matches
1 hack-saw blade

(Lindbergh was of course not the first to cross the Atlantic by air, but his flight has captured the popular imagination more than any other. And BTW, the script for Jimmy Stewart's film version captured the writing style of the book brilliantly.)
