Jonathan E. Caldwell was the creator of flying saucers (UFOs)?

These two New York TIMES clippings from August 20/21, 1949, reproduced in Flying Saucers Over Los Angeles: The UFO Craze of the 50’s by Dewayne B. Johnson and Kenn Thomas [Adventures Unlimited Press, Kempton, Illinois, 1998, Page 272] …

…tells of two flying saucers [Flying Disk “prototypes”] found in a barn near Glen  Burnie, Maryland, which is about eleven miles south of Baltimore.

It was determined that the constructs had been invented by a man named Jonathan E. Caldwell, who disappeared in the winter of 1940/1941.

The Air Force initially issued a Roswell-like statement: “…'some flying disks had been located  in Maryland,' and that Army special agents made an investigation.”

The Air Force then decided “that the two experimental aircraft … 'have absolutely no connection with the reported phenomena [sic] of flying saucers.'”

The TIMES continues “Less than  twenty-four hours earlier, however, and Air Force spokesman had said there was a 'a good chance' that the two weird devices … might be prototypes or forerunners of the flying saucers or discs.”

Roswell dé-jà vu surely.

But, more intriguing, who was Jonathan E. Caldwell and what happened to him?
