I disagree. The F-35 is a bomb truck, capable of carrying 14,000 pounds or 7 tons.  Launch Weight: (JDAM and warhead) GBU-31 (v) 1/B: 2,036 pounds (925.4 kilograms); GBU-31 (v) 3/B: 2,115 pounds (961.4 kilograms). If an f-35 had 6 GBU 31'(v) 3/B on board that would equal 12,690 pounds and that would leave room for 2 Mk 82's, weight wise. If only 6 F-35's were loaded up in this manner they would have a bomb payload of 82,140 pounds. Of course I'm not stating that this is the bomb configuration or even the number of planes used in the sortie, I have no idea on either. I am stating that because of the payload capability of the F-35 I do not find 40 tons hard to believe. Watching the video, there are at least 40 bomb hits, maybe more and if 40 GBU 31's were used that would be 80,000 pounds dropped on ISIS' ass..
