So a thousand posts later did you guys come up with a new and novel way to absolve the pilots of not being able to shoot a simple instrument approach?
Maybe I can offer some more 'solutions'?
They were possessed by demons.
An inflight abduction by aliens.
They both came off their meds at the same time.
The plane was sabotaged.
The charts were sabotaged.
The GPS sattelites were sabotaged.
The FMS was sabotaged.
The pilots were poisoned with LSD
They were so depressed, because they couldn't be married in their state, so they decided to auger it in or was it being turned down for that medical marijuana card?
or maybe they screwed up. Together, as crews do...no redundancy, both watching the same guages set up the same way, to give them both the same bad information, and they interpret it in the same bad way, flying to the same bad conclusion.
Personally I like the inflight alien abduction angle...carry on.
