I laugh at the claim that if you can't explain it simply you don't know it well enough. Cutting out some bits of card and sticking them together constitutes a pretty simple explanation of the problem, wouldn't you say?
I thought it was a wonderful concrete model using cardboard.
I've worked in educational outreach and explained eclipses, day and night and the seasons to young children. I've always used 3D models, so on your part it was text book. Seriously, it was brilliant, and solidified the orbit and VAB problem in my mind that little bit more.
The problem with any explanation is not how simple the explainer makes it, it's how well the questioner understands it.
In fairness it's a bit of both. Having said this, the explanations have been differentiated through words, diagrams, videos and your model. The contributors here could have done no more. It's down to Tim now.
This leads me to conclude either Tim does not understand or else he knows damn well he is wrong and is just getting his kicks, thinking we're jumping through hoops and getting all flustered.
There are a few possible scenarios. It has been said in this thread that dyed in the wool HBs would not even be debating the orbital mechanics. If Jarrah White was here now, I am sure he would agree with our explanation of the TLI orbit, but disagree on the radiation protection. I am beginning to question the true reason for Tim's presence. I find the obnoxious and condescending tone, punctuated with military maxims, tiresome now.
