The Rise & Fall Of The Boeing 727
The story of Boeing's narrowbody trijet.
Mark Finlay - 12 August 202
While we can thank the British for taking us into the jet age with their four-engine De Havilland Comet, Boeing firmly put its mark on jet travel when Pan American Airways introduced the Boeing 707 in 1958. The long-range jetliner can be credited with shrinking the world when it was deployed on transatlantic and transpacific routes. Yet, there remained a void in the marketplace for a jet aircraft for nearer-to-home travel.
Once the Boeing 707 program was up and running, the Seattle planemaker turned its attention to building an aircraft suitable for short to medium-range flights. The answer was a shrunken version of the 707 that could operate from shorter runways that they called the “Boeing 720”.

The Problem With The Boeing 727’s Rear Door
by Nicholas Cummins - July 14, 2020
The Boeing 727’s rear door, or otherwise described as the rear ventral airstair, could be opened mid-flight. Unlike other doors on the 727, there was no mechanical preventative stopping the rear door being opened while in flight and, say, a passenger jumping from the plane. This very scenario famously occurred with the D.B. Cooper Hijacking back in 1971.
DB Cooper Case Could Close Soon Thanks To Particle Evidence

It’s one of the strangest unsolved cases, and even though the FBI closed their investigation back in 2016, this may be the year it cracks wide open. On November 24, 1971, Dan Cooper, who would become known as DB Cooper due to a mistake by the media, skyjacked a Boeing 727 — Northwest Orient Airlines Flight 305 — headed from Portland to Seattle.
During the flight, mild-mannered Cooper coolly notified a flight attendant sitting behind him via neatly-handwritten note that he had a bomb in his briefcase. His demands were a sum of $200,000 (about $1.5 M today) and four parachutes once they got to Seattle. Upon landing, Cooper released the passengers and demanded that the plane be refueled and pointed toward Mexico City with him and most of the original crew aboard. But around 30 minutes into the flight, Cooper opened the plane’s aft staircase and vanished, parachuting into the night sky.
In the investigation that followed, the FBI recovered Cooper’s clip-on tie, tie clip, and two of the four parachutes. While it’s unclear why Cooper would have left the tie behind, it has become the biggest source of evidence for identifying him. New evidence shows that a previously unidentified particle on the tie has been identified as “titanium smeared with stainless steel”.
