Well, I have flown a small turbo prop and a B-747.
The prop job was fun and I enjoyed it.
(DHC-6) Spent 2000 hours in the thing.
After a while it got kind of, uh, easy.
Got over 5000 hours in the 747, a nice machine for sure. Fun to fly, easy and stable, but go into Bombay at night in the monsoon season at max landing weight, then you may have to concentrate on the task ahead.
In other words, it can be challenging and therefore satisfying.
The pay check and days off also makes it a good deal.
If ya turn it down....Your decision, but ya may regret it later unless ya are Chuck Yeager and get a call like that every day..
If ya get tired of the 747, well, quit and go back to the turbo props. Not sure you can go the other way.
No, size does not count, but good flying does, and the B-747 is good stuff.
(Did AACS call ya?)
