While there are many worthy candidates, your promise of more WTF's has me intrigued, and might just win me your vote.
Could we get an example of said WTF?
Jack Parson's, born in 1914, died in 1952 at the age of 37.
Jack Parsons was one of the original rocket scientists, he was also a chemist, and was the founder of the Parson's Jet Propulsion Laboratory which is still in use today by the U.S government.. He invented the first rocket engine to use a castable, composite rocket propellant. He pioneered the use of both liquid-fuel and solid-fuel rockets. His work was instrumental in NASA's later effort to put man on the moon.
In fact, there was a crater on the moon named after him, Parson's crater.
By day he was a propulsion scientist working for the U.S. government, by night he was a Thelemite occultist who studied under his friend Aleister Crowley. He can be seen on the right here and his friend Crowley on the left as they prepare for a ritual.
There was a book later written about him called Sex and Rockets.
In the 1940's Parsons and Crowley attempted to open a portal to hell in the desert, the ritual was called Babylon Working. Parsons had a house in Pasedena that served as the headquarters for Crowley's secret society known as the O.T.O,
Ordo Templi Orientalis. There were stories of orgies and black magic rituals all through the nights, by day he was a working rocket scientist.
In 1918, when Parsons was only 4 years old, Aleister Crowley performed a sex magick ritual called The Almalatrah Working. During this ritual he encountered a being he named Lam and who is pictured below.
This drawing first appeared in an exhibit in 1919 and was long before the appearance of grey aliens was in the public psyche. This was almost 30 years before the Roswell Incident. Thing is, Crowley was doing what we would call blood and sex devil magic when he supposedly encountered this being. Later when he became friends with Jack Parsons they did a long ritual in the desert where it is said that a portal opened up and something came through.
Babylon Working was performed by Jack Parsons and Aleister Crowley in 1946. In 1947, less than a year later, the Roswell incident ocurred and UFO's and grey aliens have been in the public consciousness ever since. So when you look up at the moon at night, you won't be able to see Parsons crater because it is on the dark side of the moon but understand that an occultist who delved deeply into the dark arts created the propulsion systems that later put man on the moon and may have unleashed the Greys on Earth. There is much more to the story but it would be too long. Maybe sometime I'll get the chance to tell the full story.
