@ 21:26 UTC : Long day at the office, almost 8 hours in place and still at it.

@ 23:05 UTC : Flying back to base so still a bit of flying to do and then there's the hard part : landing and that's just the crew in the cockpit, there's also the techs in the back who've been glued to monitors and what not.
So we're talking 10-11 hour shifts.
