Still don't know what's going on. Something's happened to Earth, something's happened to the colonists, Bamber is either planning a revolution or the construction of a summer home, there's a bacon black market and plenty of joking amidst the potential death of everyone on the arriving transport.
What I don't get is why the transport couldn't talk to anyone on the planet till they were in orbit. The leader of Bamber's people talks about having been able to communicate with Earth up till five years ago. So you're capable of communicating with a distant planet but not an approaching spaceship between you and that planet? Because it's all a big surprise. Oh! You're in trouble? Well, tally-ho and all that. Stiff upper lip and raise those thermal shields old bean!
How about some warning? Hi, we're a year out and we've lost contact with Earth and sustained some damage. How about we get all our people together and talk about possible solutions because nobody wants all of the colonists and supplies on board to burn up on re-entry, right? Any thoughts my fellow human beings? Since you're the advance colonial expedition with a zillion great minds twiddling their thumbs.
