At the same time, many modern microlight pilots would probably need less training to get into a C152 than into one of the tent/lawnmower hybrids which personally I think are the most fun flying machines to be found in the microlight fleet!
Ah well, we know the rules, they've now stayed pretty much the same for a reasonable number of years - so we can all work with it.
On the other hand, we used to see 1-2 perfectly serviceable microlights written off each year by high hour "heavy metal" pilots who refused to acknowledge and learn about the differences. Since microlight differences training became mandatory, those accidents have pretty much disappeared. 'Tis an ill wind which blows no good at-all, and you have to draw lines somewhere.
