Agreed- NPPL would be a great opportunity ....for a small substandard minority... but a practically useless alternative for anyone serious.
And, as the genius who started this topic worked out, it couldn't be any cheaper to fly with NPPL. It should be more expensive, as the hirers and insurers will be accepting a higher risk, of damage/loss claims, with NPPL pilots.
Also, with the price of a proper PPL course package now under £3k abroad, it will still be much more expensive and take longer to train here, even for an inferior NPPL.
