Anything that wasn’t vaporized was likely launched out into space at speeds exceeding escape velocity for Earth’s gravitational field by aat least a factor of 6. So if there was anything left after the explosion and wind friction, it’s out in space, probably moving towards the sun.
The best part of that story is that the engineer on the project initially rejected the metal cap, because he knew it would not do anything to contain the blast. His supervisor overruled him, and insisted they install the cap. The engineer complied, but also ensured a high speed camera was trained on the cap to capture just how spectacularly stupid his manager was.










Yes, that’s why most people believe it vaporized completely.
