What to remember
On November 18, 1966, at Yuma, Arizona, a gun sent a projectile 180 km up. The weapon was Project HARP's 410 mm (16 in) space gun prototype.
The projectile, a Martlet 2, weighed 180 kg (400 lb). Its height of 590,000 ft, or 110 mi, set the world record for a cannon-fired projectile.
The shot counts among flight altitude records, alongside those of planes and balloons. Only some of those records were certified by the Fédération Aéronautique Internationale, founded in Paris in 1905.
