I got this information from NTS, who got it from Jim Stone:
"Two minutes after take off, the transponder, communications, and lights on the aircraft were shut off, obviously via remote. It flew in this hacked configuration for approximately 4 minutes and 30 seconds before, in error, Iranian ground forces mistook it for a cruise missile and shot it down, with Iran's top nuclear physicists aboard. The plane was sent out during a no fly order to get the most important people (and their families) out of Iran before a war broke out, which Iran was expecting."
I can believe this scenario. Greencrow has done good writing on this topic as well, and offered this link from sputniknews.com:
