As Musk outlined in the presentation video, the BRF can be configured to carry up to 800 passengers on suborbital flights and 100 in Mars transit configuration. The BRF itself is much lighter than an A380. I am not going to debate every possible "what if's" that the luddites raise. Suffice to say, change is good, and many things about his model need work and testing in orbital and Martian service before the relevant authorites are going to grant him a passenger license. Time will tell. This is my last post on this topic.
