The distinctive list??

1. DC3 and military equivalents. Too many stories of the "over use" capabilities of the planes and their long (and continuing flying history)
2. 747 - nothing else looks like it. It changed commercial air travel. The 380 is eliminated by the C5A.
3. Concorde - The quintessential faster than sound plane. But this plane eliminates the large stealth bombers
4. The large 1930s/40s flying boats. The first overseas flights.
5. The B36 - Anyone who saw one fly overhead would not forget it. (I did)
6. A toss up between the Spitfire and the Zero
7. A toss up between the U2 and the SR71

Happy wandering
