And the explanation will undoubtedly be that Joker swooped in to rescue them and leave Shep for dead like the audio files left indicate (where Joker coming in on the Normandy and shooting at Harby was cut out because of course, we don't want to see cool shit like that).
I want to see what happens when a spaceship swoops down and grabs people, without slowing down.
I think it would be messy.
