Raise the Arrow: Discovery of an Avro Arrow test model at the bottom of Lake Ontario

Source: CTV New

Between 1954 and 1957, nine Avro Arrow models, scaled at one-eighth size or about 3 m (9.8 ft) long, are believed to have been launched, using rockets, over Lake Ontario from Point Petre in Prince Edward County, Ontario as part of the process for testing the hull design. (Two others were launched in Virginia.) They travelled at supersonic speeds as onboard sensors sent data back to shore. After many attempts to find the models, a new search was started in late July 2017. The Raise the Arrow project was a joint venture by several companies, the Canadian Coast Guard and the Royal Canadian Military Institute. A Thunderfish autonomous submarine, equipped with an AquaPix interferometric synthetic aperture sonar, was being used to survey the relevant area of the lake bottom. Any scale models found will be restored and displayed at the Canada Aviation and Space Museum in Ottawa and the National Air Force Museum of Canada in Trenton, Ontario.

• Years ahead of its time in technology
• Cancelled through political influence

In my experience with governments ... if they have something that one million to make and didn't work versus something that costs ten thousand dollars and does work they will throw them both out and and buy something that costs 100's of millions and doesn't work.
