In the first article, Gen Everhart is quoted as saying:
“Think about this. Thirty minutes, 150 metric tons, [and] less than the cost of a C-5,” he continued. In comparison, it would take the service’s cargo aircraft take anywhere from eight to 10 hours to get to the other side of the world.
What cost is he talking about that makes the BFR cheaper than a C-5?
Unit cost, BFR: US$335 million, C-5C: US$129.17 million
Cost per launch, BFR: US$7 million, C-5C: ??? but it has to be less than $7M to fly half way around the world.
