Odd - it used to be during Reftra (refresher training assessment) on a ship one of the things they would do is eliminate all the electronics and force the crew to go back to basic manual things such as line of sight/celestial navigation, semaphore/flashing light comms, manual/gas powered pumps, hand loading munitions, etc...I’m guessing since training has supposedly gotten so bad that they’ve since abandoned a lot of the basic backups.
