How about requiring airline pilots to do say aerobatics training - on a regular and ongoing basis. This would be really, really cheap compared to any real flying time training on an airliner. I suspect maybe even a lot cheaper than a simulator - by factors or even orders of magnitude.
Of course, probably inevitably, some trainees will die during this process.
What does the team think?
