Good thing we are using drones as recon aircraft these days. Can you imagine the that would have ensued if the Iranians were to capture a live pilot?
The Iranians can sell the drone to whom ever they like, but it's not like the buyers don't already have stealth technology of their own. The knowledge to design stealth engines for aircraft is already out there, that's old news. The problem is funding projects like that, which only the US can do.
Also, LOL @ the picture of the drone. You would think that the Iranians would at least try and make it realistic. There is no damage to it at all.
