Not to mention a fewLockheed airliner of one passenger types, such as:
* P-38 Lightning
* P-80 Shooting Star
* Lockheed XF-90
* Lockheed U-2
* QT-2PC PRIZE CREW
* Army-Lockheed YO-3A
* A-12 Oxcart
* SR-71 Blackbird
* D-21 Tagboard
* F-117 Nighthawk
* F-35 Joint Strike Fighter
* Lockheed X-27


"Passenger" is generally defined as a person that travels in a conveyance
without participating in its operation. Your stretching that quite a bit
with this list. But tell me, who do you consider to be the "one passenger"
on the D-21?
