Learning Channel & the Hunley

In a program on the CIA they spoke of bombing Hiroshima and showed a B-52. They showed a B-36 when the narrator was speaking about the U-2.
On “Structures” a program about about nuclear submarines, they said that the Hunley “barely damaged the Houatanic” and was “sunk by it’s own towed torpedo”. The Hunley sank the Housatanic with a torpedo on the bow, the first sub to do so, and was swamped trying to retrun to harbor.
Do these guys just make stuff up as they go along, or what?
