14th of August 1947

We all heard the name Chuck Yeager, the first man to break the sound barrier in 1947. But the name Bentleigh (Flt. Lt. Bentleigh, Royal Australian Air Force) is far less famous. Non the less he was the man that broke the sound barrier in the sky above Avalon (Victoria, Australia) for the first time over Australia in an Australian built F-86 Sabre On this day in aviation history in 1953.


The North American F-86 Sabre (Sabrejet) was the first swept-wing fighter that could counter the Soviet MIG-15 swept-wing fighter. They regularly faced off during the Korean war.

The highly popular fighter was produced in great numbers, and production would only come to an end after 9860 aircraft (all versions combined) rolled off the production lines in different parts of the world.

The F86-A flew its way into the record books for the first time in September 1948 when USAF pilot Richard L. Johnson reached a speed of 583 knots (unknown at which altitude) (1080 kph / 671 mph)/ A Canadian built F-86 Sabre (the Mk 3 version) broke the sound barrier on the 18th of May 1953 piloted by Jaqueline Cochran, making her the first woman to break the sound barrier. The F-86 was built in many different versions and the family tree below gives a nice overview although more than 30 versions were produced altogether!

A total of 29 nations used the F-86 over the course of the aircraft operational life. Italy provided 5 F-86 aircraft to the United Nations in 1963 for the UN operation in the Congo.

Currently, it is estimated that around 50 F-86 aircraft are owned (and a large part of them) flown by civil owners. With all the different variants it is difficult to give an overview of the specifications for all aircraft, so below are the specifications of an F-86F:
