As for Raxxla, nobody ever found it in the last 37 years. It is a joke Braben put in to mock with us for the entire time. I bet there is a deactivated beacon named Raxxla on some asteroid in a locked system you will never be able to enter. If somehow someone ever found it he surely got a nervous breakdown and wiped the game from his harddisk and never played Elite again.There's also the possibility that the Panther is a type of unlock/reward/found Raxxla
