Old Magazine Covers, Part 18

It's been a while since we've posted an old magazine cover...and this is a fun one. It comes from the October 1953 issue of Road & Track. The three cars are lined up at Moffett Field with what appears to be a Grumman Cougar fighter jet. Of the OSCA, Jag C-Type, J2X, and Cougar jet...which do you think could accelerate to 60 mph fastest?

Can you tell us who the owner of the J2X is? (We know the answer, but can you find it out?)
