Instead of earning the Skyjacker! medal for boarding a Banshee, currently the only airborne vehicle we have used in the Halo series (space carriers notwithstanding), the folks at Bungie have decided to give you a gold star for boarding an "aircraft," implying that multiple aircrafts will be available. Why else would they give a nondescriptive explanation for the award? O, diction be damned!
The other possibility is that the description is temporary, just like the now-renamed Cheneymania. Bungie adding another aircraft wouldn't be surprising, but so far nothing has been confirmed or sighted.
