Chilling New Theory Emerges About The Biggest Unsolved Plane Crash In U.S. History

The tragedy of Pan Am's Romance of the Skies is known as one of the most mind-boggling aviation mysteries in American history. After more than 60 years of questions, two researchers with a personal connection to Flight 7 have not stopped looking for answers...even when all known evidence pointed in a sinister direction. It's long been rumored that Flight 7's fate was no accident, and these researchers are determined to solve the mystery once and for all.

Unprecedented Power

The Romance of the Skies — aka, Flight 7 — was, to some extent, the Titanic of airline travel, and had the unofficial title of "ocean liner of the skies." The aircraft was a Boeing B-377 Stratocruiser, introduced to the world in 1947. Like the ill-fated ocean liner, Flight 7 was supposed to outlast everybody on board...

Revolutionary Aircraft

Thanks to four revolutionary engines, the "ocean liner of the skies" could reach unprecedented speeds of 350 mph. Beyond that, due to the Stratocruiser's overall size, it had a carrying capacity of 147,000 pounds. The scope of the aircraft was grand in every sense of the word...maybe a little too grand.

Fateful Maintenance Check

Prior to takeoff, maintenance had been completed on all of Pan Ams' Stratocruisers in order to strengthen them even more. Despite routine inspections, however, it's possible that the aircraft's inspectors were so reassured by the strength of the engines that they weren't as thorough as they could've been.

Day of Infamy

There were 44 individuals onboard the Romance of the Skies for its November 8, 1957 flight. With no sign of bad weather, it seemed like it'd be about as eventful as any ordinary flight. It wasn't until Flight 7 was far from land, flying over the ocean, that something happened that experts still can't explain.
