The founders of the company Spinlaunch are making a boatload, but it doesn't look as though they'll ever deliver.
Spinlaunch is a high-tech company that is attempting to modernize that biblical weapon, the sling. The Brothers Yaney are marketing Spinlaunch as the most efficient means to sling small satellites into orbit. The physics is straightforward, but the mechanics are anything but, and the financial rewards for the Brothers Yaney are out of this world. Who would think separating the wealthy from their money could be so much fun? And no, that is not the tagline to the movie The Brothers Bloom.
The physics of the Spinlaunch is simple: spin the launch vehicle faster and faster in a vacuum (to eliminate friction), then release the launch vehicle. The momentum at the point of release will be sufficient for the launch vehicle to a height of 200 miles above the Earth.
Spinlaunch's vacuum-enclosed prototype centrifuge (located at the New Mexico Spaceport) is three hundred feet across. The full-scale vacuum-enclosed centrifuge will be nine hundred feet across, making it the world's largest vacuum structure. If it does not collapse under the weight of gravity, it will collapse under the pull of the vacuum.
The Spinlaunch centrifuge will spin (10,000 gs) the 2,500-pound launch vehicle to 5,000 mph. A slight imbalance between the centrifuge and the launch vehicles or uneven wear on the critical parts would result in vibrations that could cause the structure to disintegrate. An error of just milliseconds in releasing the launch vehicle would cause the launch vehicle to touch the side of the launch tube, causing the structure to disintegrate. There would be enough energy when Spinlaunch disintegrates to destroy a small city.

Have your African Swallows been jabbed?
Thats why I would use only European swallows, they have been jabbed. Use them before they all mysteriously die
The whole news cycle is becoming one big inside joke on us
Exactly. Only a BB could survive that.
