Thanks, John, that explains a lot!

Was lucky, searching the tech report server produced
3 tech reports on those Convair tests. of the alloy

considering the speeds the planes were getting to and the heat
build-up from the friction. Aluminum alloys tend to loose their
strength becasue to the annealing effect of that heat.
believe that they were looking for an alloy that could be used.

and the F9F, was probably a test for carrier use, being exposed
to the salt air at sea.

As you know
Lockheed used Titanium to solve that annealing issue on the Blackbird.
