I'm sure we've already heard of the great Scott Manley, Shadow Zone, Matt Lowne, Hazard-ish, and Stratenblitz75. (You can also find them on the forums, @illectro, @ShadowZone, @Matt Lowne, @hazard-ish, and @Stratzenblitz75, don't tell anyone!)
But yesterday, I found a new KSP channel that is simply amazing, the name is SpaceLab, and one of their recent videos, a Mars 2020 replication, is amazing.
Which brings me to the question, what are some channels that you have found before, that did KSP in an amazing way?
