An alcoholic beverage named after Captain Sullenberger, the pilot who successfully landed a commercial airliner in the Hudson river without harming any passengers.
The drink consists of a shot of Grey Goose, dropped into a glass of water. Grey Goose represents the flock of geese that caused the engines to fail, and the water obviously represents the river in which the plane was landed.
This drink is far from ideal, likewise, so is landing a plane in the river, but it'll work in the most dire situations.
Sometimes you just have to improvise. How about a Sullenberger shot? Drop a shot of the Goose into a glass of water, and salute Captain Sully
