That and their inability to understand a simple departure procedure clearance. We missed the part leading up where they try to load up the departure clearance in the GPS and find it's not there. They then find it and completely misinterpret it:
1. They turn when not assigned a turn.
2. The appear (at least Jerry tells him to do so, can't tell if he did or not) go direct to the destination ("as filed") before appropriate.
ATC seems to have tolerated it and just gave them a DIRECT OGDEN instruction later on.
I love his disclaimer that this is for our entertainment and not intended to be instruction.
I love on every single flight he never thinks to set his altimeter or transponder code until AFTER he acknowledges his takeoff clearance. This is common to just about all of his videos.
