I think you have missed the guts of the post.
1. Embraer design and build single pilot aircraft.
2. The local authorities revise the "rules" to allow single pilot ops under certain circumstances.
3. The major concern for pax is the single pilot being incapacitated and some one else "monitoring" the aircraft systems, I.e. A flight attendant.
Don't laugh though, it's not that far off. Aircraft can already fly with out pilots. The job of a single pilot on an aircraft won't be to fly it as we do now, it will be System man agent only, UNLESS there is a malfunction.
If the pilot has a " malfuncrtion" i suspect what O'leary is thinking, and I agree the mans a complete fool, is that they will train a flight attendant to jump in and monitor the systems.
That's the funny part, imagining a cart tart, galley hag having sufficient system knowledge through months of study to jump in and take over, and all for 20k a yr, today we call that person an F/Oa year.
