Yes, it's interesting looking at the differences between how the US and Russia develop their vehicles for their respective space programmes.Well, this is how the UK's BlueStreak was designed and built: Go for the simplest design with least failure possibilities. It might not be the shiniest, but it will work and continue to work for decades. But we all know what happened there.The Americans seem to have gone for complex, expensive, brand new designs from the ground up, which they then risk-assess the hell out of (in theory at least.)
