“747 wing design fades long before that altitude.”

I guess you missed the word “modified” in my post. ;-)

That would be a very expensive and probably not very effective modification - wing design is one of the most critical thing on any aircraft. Better to put the unit on the next generation spy plane. Provided they can shrink it and then it would also be stealth.
