Giving the situation a thought:
The Super Sabre would only maintain it's hype until the presence of the starfighter in '58!
It might be some kind of jubilee, but in absence of (at least) the P-51 it can't be in connection of the second war.
If it's in connection with the first war, would the Starfighter have replaced the Super Sabre for the 40-year jubilee of the end of war late 1918.
Could it be 40-year jubilee of the outbreak of WW1 in august 1914 - Being august 1954!?
