Woah, daddy, I don't think so.
WWII 30 cal= 4000 feet per second.
50 Cal Browning from WWII has a muzzle velocity of 3000 feet per second.
That's at the muzzle, and on the ground without any wind rushing by the barrel while the plane is flying. When that bullet gets to its target which would be at least 100 yds away I'd think, it won't be traveling anywhere near that fast.
2930 fps for the heavy barrel Browning 50. Then, the pilots and gunners have to manually aim and hit a target that could easily be running over 1000mph as it passes the WWII plane. So the bullet leaves the old fighter running at 1900 mph. The F-22, assuming it's just simply running straight away and not juking at all, will be accelerating towards its top speed of 1600 mph.
So the bullet starts off at 1900, and steadily loses speed from there. It's max range is 4 miles, and that's with a huge ballistic arc, I'm sure.
I'm guessing that the bullet would have a very short time to actually catch up with the F-22 before it loses too much of its velocity and the F-22 runs away from it.
WWII pilots are used to their 50 caliber bullets having approximately a 1600 mph speed advantage over their targets...plus, they are traveling at 3-400 mph inside the gun already, so I'd guess they have to overcome the shooting plane's speed just to get out of the barrel. I don't think you'd add the shooting plane's speed to that of the bullet.
I'd love to see someone do the math on this just out of curiousity, but the bottom line is, I don't think anyone would have much success at manually aiming and hitting a supersonic F-22 with a machine gun, especially from another moving craft.
Could be done, I guess, but not with any regularity.
