A sad event, the C 150 pilot did a good job in getting down safely, that damage would certainly affect how the 150 flew. Lookout and visibility are a challenge in a 150 for all the reasons we know.
Since when has a glider not been a 'Plane'?
In Canada, a long time:
aeroplane means a power-driven heavier-than-air aircraft that derives its lift in flight from aerodynamic reactions on surfaces that remain fixed during flight
Which is why aeroplane pilots are not automatically entitled to fly gliders on their aeroplane license.
