The Curtiss-Wright XF-87 Blackhawk (previously designated the XP-87) was a prototype American all-weather jet fighter interceptor and the company's last aircraft project. Designed as a replacement for the World War II–era propeller-driven P-61 Black Widow night/interceptor aircraft, the XF-87 lost in government procurement competition to the Northrop F-89 Scorpion. The loss of the contract was fatal to the company; the Curtiss-Wright Corporation closed down its aviation division, selling its assets to North American Aviation.
The aircraft started life as a project for an attack aircraft, designated XA-43. When the United States Army Air Forces issued a requirement for a jet-powered all-weather fighter in 1945, the design was reworked for that request.
The XP-87 was a large mid-wing aircraft with four engines paired in underwing pods, with a mid-mounted tailplane and tricycle undercarriage. Two crew members (pilot and radar operator) sat side by side under a single canopy. Armament was to be a nose-mounted, powered turret containing four 20 mm (0.79 in) cannon, but this was never fitted to the prototypes.
Underneath a big clock
At the corner of 5th Avenue and 22nd Street
I stood and waited for a girl I knew
At the spot where we agreed to meet
It was four minutes of two
At four of two, I stood waiting for the girl
I was four minutes early for the date we had planned
I was planning to say I was in love with her
Just as soon as she showed for a two o'clock date
And the clock said four of two
At four of two, I was staring into space
She was not yet late, according to the clock
I was feeling nervous so I kept looking up
At the clock sticking out of the side of the building
And it still said four of two
At four of two, I began to feel tired
And I rubbed my eyes, and again I checked the time
It seemed as if the sky was growing dark
But I felt reassured when I looked at the clock
And it still said four of two
I lay my head down on the sidewalk
So in case she were coming I would have a better view
But no one was there so I stretched out
And closed my eyes for a second or two
It was four minutes of two
At once I awoke to a futuristic world
There were flying cars and gigantic metal bugs
I'd grown a beard, it was long and white
But I knew that the girl would be coming very soon
For though everything had changed, there was still that clock
