You absolutely do not need .50 to penetrate an aircraft skin. A
regular 7.62 NATO, not even AP, should do nicely.
Frontal aspect might be a bit tougher. ISTR reading about a hijack
situation where the boss bad guy was visible in the cockpit (aircraft on
the ground) so it was decided to snipe him, but the bullet didn't
penetrate the cockpit window.
