I find myself entertained that he is so annoyed at having to brake ride back into the PAS (without being asked!). Cry me a river... Admittedly that had to have been an uncomfortably loooooong flight, but the jobs not done till it's done.
Seriously? The job was done...riding brakes need not be done by the pilot, in fact it is most often done by maintainers.
Unless you've flown similar missions, I would say your opinion is mostly irrelevant. It seems much more logical to have the maintainer ride the brakes in this case than the pilot who hasn't been able to move for 13.5 hours. Heaven forbid someone has to climb up a ladder and sit in a seat for two minutes so a guy who's just logged the longest Viper mission in history can take a load off.
