Pretty common incident actually. No idea about this particular one but the standard process is a bit of a flat or "wheelbarrow" nosewheel-first landing. The plane is going a bit fast so still has flying speed and hops back into the air. Chuck in a couple of bounces and when the student finally tries to end the wild-ride by pushing the plane onto the ground, the nose-leg just gives up.
I saw one come very, very close at Hamilton, but haven't witnessed an actual collapse first-hand.
Oh well! Now over to the insurance company. Carry on, everyone else.
