Not in the air, and no-one was injured. :D

The train was carrying six 737 fuselages at the time; three stayed on land, three "ditched" in a river.
Montana Rail Link said it isn't sure how long the recovery effort will take, because it's the first time it has dealt with recovering derailed jet fuselages... ;D
What if this happens with tanks at the beginning of a war ?

That should be no different than what happened throughout WWII. Lots of tanks never arrived to the front line, or arrived only at the second or third attempt. Not so much due to derailment at the very beginning of the war, but still.
