Going safe and practical doesnt mean we don't innovate. Your US space shuttle is a great example. It end up a white elephant project that cost billion for US. Same as Zumalt destroyer.It’s this type of mindset why China are followers and not leaders in innovation. It’s why SpaceX was the first mover on reusable rockets and China is playing catch-up.
Laugh all you want now, but your going to look pretty stupid when SpaceX perfects this landing technique.
Isn't Space X aim is to make practical for every launch? Wait for it to land safe before call me again . In the meantime it just an unsafe big fire work.
