The Russians.. It was the 80s and they kept calling out MiGs (Russian built jets). They never actually said Russia, but we know what it was. Ain't nobody else have MiGs and we scrambling off the West coast to meet them. And those pilots were white so it wasn't any Asian/Arab country either.
During the graduation party, Viper calls in the newly graduated aviators with the orders to deploy. Iceman, Hollywood, and Maverick are ordered to immediately return to
Enterprise to deal with a "crisis situation", providing air support for the rescue of a stricken ship that has drifted into hostile waters.
Maverick and Merlin (Cougar's former RIO) are assigned as back-up for F-14s flown by Iceman and Hollywood, despite Iceman's reservations over Maverick's state of mind. The subsequent hostile engagement with six MiGs sees Hollywood shot down; Maverick is scrambled alone due to a
catapult failure and nearly retreats after encountering circumstances similar to those that caused Goose's death. Upon finally rejoining Iceman, the two are still badly outnumbered, but Maverick vocally refuses to leave Iceman without a wingman and manages to shoot down three MiGs. Iceman, shifting to offense also shoots one down, which forces the other two to flee. Upon their triumphant return to
Enterprise, Iceman and Maverick share newfound respect in each other.
Offered any assignment he chooses, Maverick decides to return to Topgun as an instructor. At a bar in Miramar, Maverick and Charlie reunite.
