Unused Helicopter and Biplane#

This needs some investigation.
Discuss ideas and findings on the talk page.
Specifically: Is there a way to force these to load in-game?

Although not available in-game, there are many files within the game's resource archive (PSP_GAME/USRDIR/Media.mif) referencing helicopters and biplanes.

For helicopters, the information contained within these files even extends to helicopter type, referencing the nickname "Kiowa" (found in Veh/Anim/helicopter_01.dxg), the nickname for the Bell OH-58 family of helicopters.

Files related to the helicopter present within the archive include:

Unused Milestones#

In addition to the milestones displayed when navigating to the "Milestones" menu, there are three more milestone descriptions contained within Text/us/Stunts.text.rbh that are seemingly unused.

Milestone ID	Milestone Description
STUNT_PROP_SUCCESS0	Cheese is a kind of meat, a tasty yellow bEEf.
STUNT_PROP_SUCCESS1	You are the greatest Jazz player in Yorkshire.
STUNT_PROP_SUCCESS2	You are a squashed-in French man, a naked little squashed up hairy boy.

All these descriptions appear to be references to quotes from a British comedy troupe called The Mighty Boosh.
