But that’s not all, I obtained never seen before photos and videos of some aerospikes, we’ll get opinions from some people who have actually worked with aerospike engines, look at some promising prospects and compelling concepts and by the end of the video we’ll hopefully know whether or not the holy grail of rocket engines is just waiting to be utilized or if aerospikes just simply aren’t worth it.
