Hell, a CF-100 Mk-1 clunk broke the sound barrier in 1951! I wonder if
the F89 or F94, the CF100 contemporaries could do this?? Anyway, aren't the
Yanks or Russians first at everything! Hollywood claims they are so it must
be true!

Hi Ed

You are out by a year and a later version of the aircraft.

Jan Zurakowski became the first person to exceed Mach 1 in a straight
wing aircraft with out the aid of rocket power. He was flying an Avro
Canada CF-100 Mk.4B Canuck (not Clunk as is affectionately known as)
R.C.A.F. serial number 18112.

Standard procedure for a pilot to achieve Mach 1, was to dive the CF-100
straight down from FL 450 at full power. The CF-100 was very marginal
in the supersonic breakthrough. It depended largely on aerodynamic
cleanliness of each individual aircraft whether it would break the sound
barrier. The CF-100 would hardly ever surpass Mach 1.05.

As for the Northrop F-89 Scorpion and Lockheed F-89 Starfire, only the
F-89C Starfire could exceed Mach 1 in a shallow dive.

Cheers...Chris
