I would never land the Orion. There is no point. I mean one could make the argument to repair it but if its already in space then chances are you are screwed. Orion is too delicate to be taking chances at landing, if the plate becomes damaged you better hope you can get people from earth to come repair it, as long as you are in earth orbit.
(I use chances a lot cos nothing ever goes 100% perfect, as history shows.)
Orion has the amount of power needed to carry along backup escape rocket vessels and it can carry a large 'Apollo style luna lander' for landing on mars.
The only thing the Orion would do in my book is act like the ferry, that's all. This is why I really want this mod.
And besides. I wouldnt to irradiate the landing site. Don't care if the pulse units have low radioactive fallout (mainly being airburst) figures I just wouldn't do it.
Please fix this mod if you have time.
Also computers nowadays would make the Orion much easier to work with being able to calculate ejection safe distances and wireless activation of the bombs. One may think.
