'''Context:'''
Currently, in v2.5, you are given the opportunity to sell
# both damaged and pristine captured UFOs at the same price
# to any nation no matter the distance (and not only to the one the UFO landed or crashed on).
# immediately after the UFO is secured

If the UFO is not sold at this moment, and is transfered to a yard, in order to be dismantled, then you can only
# transfer it to another yard, provided it's not full, or
# destroy it to no gain, to make room for another, more interesting UFO (less damaged, better class (scrap-wise), a new model to study).

'''Suggestion:'''
I wonder if it would be easy to add a second opportunity to sell the UFO to a nation when it's stored in a yard.
I don't see any intern logic that would oppose this possibility:
* the UFO is in the same state as when it was captured
* same class UFOs are still sold at the same price as when the one that's stored was captured
* distances are not a concern


Looking at a UFO-yard window, we see that the Transfer button is not that useful, because there's a Transfer tab too, and as far as I know, they do the same. Hence, the Sell button could replace this Transfer button (see joined screenshot).


Perhaps, if it's not wanted to summon the same Sell UFO window as when the Secure mission is won,only one nation could simply be possible: the one the yard is build in. The player would thus not be asked whom he wants to sell.
Likewise, price doesn't need to be the same: let's say that the nation consider it's now normal business, and charge a tax.
The same notice would appear in the log (except that the UFO number is now lost?)
