Shock Diamonds, Low Altitude, Vapor Cones and Glorious Roar. Oh my!

That’s the best vapour pullin I’ve ever seen.

Bet in person that was a real goose bumps maker!

Few sights are as awe-inspiring as a B-1B Lancer streaking through the skies with its afterburners engaged, leaving behind a mesmerizing condensation blanket. This phenomenon, captured in a striking video, showcases the incredible power and agility of this iconic bomber aircraft.

The B-1B Lancer, developed by Rockwell International and now operated by the United States Air Force (USAF), is a supersonic heavy bomber renowned for its speed, versatility, and precision strike capabilities. It was designed to operate at high subsonic speeds and low altitudes, making it a formidable asset in both conventional and nuclear roles.

One of the defining features of the B-1B is its four General Electric F101-GE-102 turbofan engines, each equipped with an afterburner. When the afterburners are engaged, they inject additional fuel into the exhaust stream, dramatically increasing thrust and propelling the aircraft to supersonic speeds.

The Condensation Blanket Phenomenon

The video in question captures the B-1B in a high-speed pass, with its afterburners ablaze. As the aircraft accelerates, it generates an astonishing visual spectacle—a condensation blanket. This phenomenon occurs when the combination of speed and moisture in the atmosphere leads to the formation of visible vapor clouds around the aircraft.

The Science Behind Condensation Blankets

Condensation blankets are a result of the Prandtl-Glauert singularity, a physics phenomenon associated with high-speed flight. When an aircraft approaches or exceeds the speed of sound (known as Mach 1), it generates a rapid change in air pressure and density around its surfaces. This change causes moisture in the air to condense, forming visible vapor clouds.
