This is a clip from historical Film No 1119 produced in 1923 by the US Army Signal Corp.
The caption says:
“A smoke curtain – An important new chemical warfare development. Hanging a curtain half a mile long in 18 seconds”
This 1923 film shows an aircraft spraying a trail where some of the chemicals rapidly descend to sea level to form an opaque vertical curtain.
Observers have seen an increasing frequency of chemical warfare and other experiments in our skies since the 1930’s.
Spraying Agent Orange during the Vietnam War demonstrates the military has been developing more sophisticated chemical warfare operations using aircraft since 1923.
As aircraft performance, altitude and fleet numbers have increase, observers are seeing a skyrocketing number of chemical experiments in our skies.
The advent of the internet and digital cameras has created a spontaneous network of observers around the world who share their many observations of bizarre contrail emissions on youtube.
Complete Film No 1119: “Aerial Bombing of Obsolete Battleships”.
A look at vintage ships and aircraft as General William “Billy” Mitchell hosts this demonstration of aerial bombing of obsolete World War I era battleships. Tests like these paved the way for major advances in aerial and naval warfare. High explosive, smoke, gas, and chemical bombs are used along with a demonstration of a smoke curtain dropped from an airplane. Original title: “Aerial Bombing of Obsolete Battleships”.
The film opens with a shot of General Mitchell and dignitaries aboard the U.S. mine “planter”, “General J.M. Schofield”. Other ships shown (but not targets) are:
- Secretary Denby’s yacht, “Sylph”
- USS Henderson
- USS Pennsylvania, flagship of the fleet
- USS Olympia, Admiral Dewey’s flagship at the Battle of Manila Bay (the Olympia, launched in 1892, is the oldest steel warship afloat in the world and can be seen at the Independence Seaport Museum at Penn’s Landing on the Delaware River in Philadelphia, PA.
