If I can add some fuel to the fire- If we use the chiseled in stone metaphor for 4 American aviation icons I offer: Orville, Wilbur, Lindburg, Armstrong.....
I think these 4 have ther best chance of being long, long remembered...
Note I did not say "best" or most inovative or influential- that may be a different list. It is not always about personal contibution, invovation, etc. Some are just held higher in the public conscious.
