Bullcrap - that’s not how aircraft or aerial weaponry works.

When the F-11 in question was struck by it’s own cannon rounds it was moving about double the speed of those cannon shells because the velocity of the cannon shells had decayed to about 400mph - a speed even a late-WW2 fighter could easily achieve.

The Grumman F-11 is not even an especially fast aircraft by late-50s standard. The MiG-19 was introduced almost at the same time as the F-11, and it was already significantly faster.

Remember - they didn’t throw Martin Skhreli into rich-guy’s prison because he caused thousands of people to die by raising the prices on lifesaving medicines out of reach of poor folk… no, no, no, they threw him into rich guy’s prison because he embezzled some of his fellow rich parasites’ money.

The way it looks is the way it is.
