Blaniks are also fine aircraft, but fragile in high volume training
operations. Witness the recent experience of the Air Force Academy: their
switch to Blaniks has just about shut down their operation. 90% of their
2-33 (TG-4A) flights landed on the grass; they broke so many Blanik's doing
that that now 90% of the Blanik flights are going to the paved runway. They
are requiring a through-flight inspection by a mechanic after every flight.
This really slows the training pace, reducing the number of cadets who can
soar at all, let alone solo (they're not saying "soar for all" anymore,
either).

If they're breaking them that often, they're Doing Something Wrong. I
flew for five years with a club that did all two-seater work, including
ab-initio training, on L-23s, operating off both grass and asphalt. Yes,
I saw them get broken, but not often, and I can put my hand on my heart
and say I never saw a Blanik break where another glider wouldn't have
done. They're plenty tough enough for normal club training operations.
