Firing lasers up the backsides of rockets could accelerate them faster without requiring e...

Russian scientists have proposed a novel way to accelerate a spaceship while in flight – firing a ground-based laser up its backside. The new technique uses a plasma flow caused by laser ablation to increase the exhaust efficiency of a traditional rocket propulsion system, and could theoretically accelerate an aircraft beyond Mach 10.  Read More

The W88 ALT 370 warhead was dropped from a crane to simulate a loading accident
