In the early 1960s, deployment of rocket-powered ejection seats designed for use at supersonic speeds began in such planes as the Convair F-106 Delta Dart. Six pilots have ejected at speeds exceeding 700 knots (1,300 km/h; 810 mph).
A typical value of e (exact value depends on the club) would be about 0.83. According to the equation above, the resulting ball speed (assuming a solid hit) would be: V = 110*(1+0.83)/(1+46/190) = 110*1.47 = 162 mph.
