How do we know it was carrying a nuke? Just because they said they had one on board doesn't mean they did?
Agreed, we can't know, we're just reading the newspaper. And frankly, the amount of spelling mistakes and misunderstandings there is more worrying to me than Russian bombers:
air-dropped “seek and find"d (sic)
alerted after cockpit conservations (sic)
We "downloaded" (my quotation marks) conversations from the crew
and the "nuclear missile" is most likely a reference to some kind kind of air-dropped torpedo (I have yet to see a flying submarine).
