Uncharted Drakes Fortune Easter Egg - Crash Bandicoot Reference

In the video sequence after the first playable section of the game, if you look closely enough at the side of Sully's plane you will see it is called "Hog Wild".

This is a reference to the first Crash Bandicoot game (also developed by Naughty Dog) in which one of the levels is called "Hog Wild". This is most easily seen when Drake and Elena are getting into the plane from the water.
