Tunnel flight

A staple of the Ace Combat series, tunnel flights are, obviously, moments where the player has to fly into a tunnel barely wide enough for the plane to pass through. Tunnel flight moments usually occur during the game's climax. The first tunnel flight moment in AC history occured in Ace Combat 2: near the end of the Battle of Fortress Intolerance, Scarface Squadron flight lead Scarface One had to fly through a vent shaft into the bowels of Fortress Intolerance in order to destroy the Usean rebels' final Submarine Launched Ballistic Missile. The missile was ultimately wiped out, thus ending the Usean Rebellion once & for all.
