Then at 150,000mph it might be 85 billion miles from Earth, barring any kind of drag or impact. It would have been traveling too fast to have burned up on its way out of Earth's atmosphere owing to its size (4 inches thick and 2ft across) and weight,
2000lbs. Lots of smaller meteorites make it to Earth without vaporizing, through at slower speeds. This would be the first man-launched object to break orbit. Most thought it would have been vapourized, but you'd expect they'd have at least seen that
event happen, like a meteor burning up. Small objects have been fired at 36,000mph on Earth without having been vaporized. It would have also depended on if the cap stayed flat or went sideways providing a much smaller aerodynamic profile. Where they
still doing underground testing, they could purposely launch a near-solid projectile this way just to see what might happen. I guess N. Korea could do it now.
Oddly, there appears to be no pictures or motion-picture film preserved from observation of the event.

67 km/s at surface air pressure would result in forces that exceed the
material strength of iron. And that's not considering the
acceleration. Or the fact that the plasma fireball would have been
well ahead of it, and that's what it would have been traveling
through.

It's atoms.

It would be out of the atmosphere in 1/3 of a second. I don't believe it is long enough to completely vaporize a solid iron object. I don't know how fast the fastest meteorites have hit the atmosphere, but if they are of any size, some of them make it
through.

You can't accelerate a piece of iron like that to that speed without
destroying it. You are several orders of magnitude beyond its material strength.

Meteoroids can encounter the atmosphere at similar speeds, but they
encounter it where the air is MUCH thinner. As a result, they fragment
and burn at a high altitude, and anything that survives to the ground
is either traveling at terminal velocity, or if sufficiently large to
remain hypersonic, just a few kilometers per second. Nothing smaller
than an asteroid can still be traveling tens of kilometers per second
at ground level.
