Fearless Tower
Touchdown! Greaser!
I'm interested in this discussion, but I wonder if we just accept that there is a zone where our options are limited to a "best we can do" return to Earth.
You have to. You cannot eliminate every risk. You can mitigate, but some residual risk will always remain.
Even a policy of 'climbing in the pattern to 4500' is not going to eliminate the risk if the failure or issue occurs early in the initial climb.
