Daffyd, you make a very valid point in that in considering an aircraft purchase it must be designed from the outset with safety in mind. There aren't any homebuilts or LSA varieties that I have seen that really can claim this. New certified "safe" aircraft are simply priced too high for us recreational pilots. I.E new 172 is close to $500k, and just how robust and safe is it really? Granted, a lot safer than a RV, Zenith, Tecnam etc, but a high impact accident I think is a hard thing to survive regardless of aircraft design.
Clearly, operating a Drifter or Thruster carries a higher risk than a 172, protection wise that is. But the pilot must be aware of this and operate them accordingly.
Is there any recreational aircraft available, for a reasonable price, that has a higher crash worthiness inherently built in, that is readily available?
