Airforce is a period-7 billiard table oscillator discovered by David Buckingham in 1972.[1][2] The rotor consists of two copies of the rotor of burloaferimeter and resembles an aircraft carrier in one phase.
Goldtiger997 found a 85-glider synthesis for this oscillator on March 7, 2020.[3]
A stator variant of airforce has occurred semi-naturally.
