XCOM EU Capturing an airborne alien spacecraft. While in flight

[omega2550]

I was wondering is it possible to capture an alien spacecraft while still in flight ??

 

If so how near would it be to capture and some of it's alien crew alive.

 

Now that would be a neat mod to add to Long War.

 

What would it be like to be lading at your X-COM HQ in an alien spacecraft. Mostly intact and not hauled back piece meal.
