I'm sure Weavers parents are really glad of modern autopilots, they are so good that not only have they helped Weaver stay alive for so long but they are now so simple that they would even allow a proverbial one eyed, spotty ginger fat geek to do a difficult flight.
One day they will advance to the point that they can do fuel and endurance calculations without the need for a qualified pilot (for the journey) to cross check them.
Maybe this was the real crew on the Seneca V flight - I guess we will all never know
