The FBI recovered a 495 year old (!) manuscript signed by Spanish Conquistador Hernando Cortés that was about to be sold at auction in Massachusetts.

That should finally be sufficient information to draw some conclusions about Hernando Cortes.

Idiot, imbecile, and moron were, not so long ago, used in a psychological classification system, and each one was assigned to a fairly specific range of abilities.
Idiots. —Those so defective that the mental development never exceeds that or a normal child of about two years.
Imbeciles. —Those whose development is higher than that of an idiot, but whose intelligence does not exceed that of a normal child of about seven years.
Morons. —Those whose mental development is above that of an imbecile, but does not exceed that of a normal child of about twelve years.
— Edmund Burke Huey, Backward and Feeble-Minded Children, 1912Only non-witches get due process.

tipa-Caproni: Italy’s Bizarre “Flying Barrel” , 1932
The Stipa-Caproni was an experimental airplane designed by the Italian aeronautical engineer and aircraft designer Luigi Stipa, and built by Caproni, an Italian aircraft manufacturer. Despite looking like a cartoon air plane, the Stipa-Caproni could fly, and was briefly studied by NASA.

Mark, that's great.
This would make a useful topic for a physics question from hell! Try and derive an equation to describe the position of the ball over time.....

As is often the case in here, I had to look up 'micrometeorite'. This is what Wiki says:
"A micrometeorite is a micrometeoroid that has survived entry through the Earth's atmosphere. Usually found on Earth's surface, micrometeorites differ from meteorites in that they are smaller in size, more abundant, and different in composition. The IAU officially defines meteorites as 30 micrometers to 1 meter; micrometeorites are the small end of the range (~submillimeter).[1] They are a subset of cosmic dust, which also includes the smaller interplanetary dust particles (IDPs).[2]
Micrometeorites enter Earth's atmosphere at high velocities (at least 11 km/s) and undergo heating through atmospheric friction and compression. Micrometeorites individually weigh between 10−9 and 10−4 g and collectively comprise most of the extraterrestrial material that has come to the present-day Earth."
