On February 20, 1959 — a day Canadians still call "Black Friday" — Prime Minister John Diefenbaker cancelled the most advanced interceptor on the planet, fired 14,500 people, and ordered every prototype destroyed. Then, for good measure, he had the blueprints shredded.

The Avro Arrow remains Canada's great aviation what-if — a Mach 2 superfighter killed by politics, missiles, and spectacularly bad timing.

Built for the Bomber Threat

In the early 1950s, Canada sat directly beneath the polar route from the Soviet Union to North America. Soviet long-range bombers — the Tu-95 Bear, the Myasishchev M-4 Bison — would cross the Arctic and descend on Canadian and American cities. Ottawa needed an interceptor that could reach Mach 2 and 50,000 feet to engage those bombers as far north as possible.

Avro Canada's CF-105 Arrow was the answer. A two-seat delta-wing interceptor spanning 50 feet, it was powered initially by Pratt & Whitney J75s, with plans to switch to the domestically designed Orenda PS.13 Iroquois — a monster producing 26,000 pounds of thrust with afterburner. It carried weapons internally, in a bay that showcased the delta wing's massive internal volume. In testing, it reached Mach 1.96 with the interim engines. The Iroquois-powered Mk.2 was expected to exceed Mach 2 comfortably.

Black Friday

Diefenbaker killed the Arrow on February 20, 1959, citing $1.1 billion in total costs and arguing that missiles — specifically the CIM-10 Bomarc surface-to-air missile — could do the job more cheaply. The 14,500 Avro employees who lost their jobs that day were joined by another 15,000 at 650 subcontractors across Canada.

Then came the destruction order. All five completed aircraft, all components including the Iroquois engines, all blueprints, drawings, and nearly all technical data were cut up for scrap. The thoroughness was methodical and, to many Canadians, unforgivable.

Test pilots praised the Arrow’s handling, with chief test pilot Janusz Zurakowski describing the aircraft in glowing terms after flying it.

Canada's Loss, the Moon's Gain

Jim Chamberlin led a group of 25 Avro engineers who joined NASA's Space Task Group after the cancellation. The group eventually grew to 32 — collectively known as the "Avro Group." Chamberlin was instrumental in proposing Lunar Orbit Rendezvous as the mission mode for Apollo — the method ultimately used to reach the Moon. Owen Maynard, a former Avro stress engineer, became the primary designer of the Apollo Lunar Module.

Canada killed its greatest fighter. Thirty-two of its best engineers went to NASA and helped put men on the Moon.

“The development of the Arrow aircraft and Iroquois engine should be terminated now.”

The Treasure Hunt

Before the Arrow flew, Avro launched nine 1/8-scale free-flight test models over Lake Ontario. In 2017, the "Raise the Arrow" expedition found one on the lake bottom near Kingston. It was recovered in 2018, and it is now on display at the Canada Aviation and Space Museum. In 2020 the project located fragments of a second model before the search wound down.

Sixty-seven years after Black Friday, Canadians are still diving into Lake Ontario looking for pieces of the dream their government destroyed. The Bomarc missiles that replaced the Arrow were useless. The Soviet bomber threat was real but evolved into ICBMs anyway. And the most advanced interceptor of its era ended its life under a cutting torch.

Some cancellations become footnotes. This one became a national wound.
