The pen's resemblance to the sleek fuselage of the P-51 Mustang, a fighter
plane used extensively during the war, had no bearing on its name; but
Parker took advantage of the coincidence by comparing the pen and the plane
in its advertising. Additionally, a pilot who is suspected of falsifying
flight records in his logbook in order to overstate his actual experience is
said to have logged "P-51 hours," relying on the ambiguity of the term
"P-51" to avoid directly confronting the suspect.

That's the story I've heard.
