List of Cuba–United States aircraft hijackings
Aircraft hijacking incidents between the United States and Cuba were at their height between 1968 and 1972. These incidents have variously been attributed to terrorism, extortion, flight for political asylum, mental illness, and transportation between the two countries as a result of the ongoing antagonistic Cuba-United States relations and the Communist government restrictions against Cubans attempting to leave Cuba.
