Did I miss something, but (given that the prog was aimed at the average TV watcher) did it actually explain what the motivations or advantages would be to FR in carrying lower levels of fuel (but still legal). ?
Users of this forum might understand this (or consider it to be bleeding obvious), but it would need pointing out in words of one syllable with a clear connection established between fuel-loads and operating costs for the message to have any real impact on the average viewer.
