Not to derail the conversation but I searched real quick on Dahl and realized he was part of the Maury Island story and then read this:
On the 1st of August, two Army Air Corps Officers, 1st Lt. Frank M. Brown and Capt. William L. Davidson, who had been sent to investigate the incident, were killed when their B-25 carrying the photographs and some of the alleged UFO residue mysteriously crashed.
--------------------------------------------------------------------------------
WHAT HAPPENED NEXT?
On the 3rd of August Kenneth Arnold's airplane was sabotaged, and he narrowly escaped being killed in a crash. 13
Paul Lance, the Tacoma Times reporter, died in "...two weeks ... and the cause of his death was not clear...he lay on a slab in the morgue for about thirty-six hours while the pathologists apparently hemmed and hawed." 14
A short time later, Ted Morello, The United Press stringer at Tacoma, also died. 15
Ray Palmer, Editor of eight Ziff Davis Publications, and who had increased circulation of Amazing Stories from 80,000 to 130,000 and initiated the Maury Island investigation was fired. 16
The Tacoma Times, a newspaper in business over 40 years went out of business. 17
If all this is true it's really trippy considering I've only read about the original plane crash which gets quickly dismissed as an accident. But when coupled with these events starts seeming less so.
