-Indeed. And then there were the “X” planes ... X-1 thru 5, X-13, X-14, and X-15.-

And the bombers;
A-3 Sky Warrior
B-47 Stratojet
B-57 Canberra
B-58 Hustler
YB-60

And of course the B-52 BUFF. 742 were built and 58 still in service (there is an additional 18 in reserve). The USAF expects the B-52 to be in service into the 2050’s. Amazing!
