Indeed.
There's something quite intriguing about the concept.
I consider there are too many variables at play in TO and LDG to make this viable, such as THAT headwind isn't going to stay a headwind for very long on the rollout. Each aircraft will vector differently along the ground around the runway according to gear wheel base and speeds. How about the dead wings behaviour?
Like I say, it's intriguing and I certainly never dismiss the "extraordinary" on first sight - it's how we evolved by being immensely open minded - but I think far too many variables RW that would make it too ambiguous to operate with any degree of safety and practicality.
Thanks for posting.
