Looks like he did a pretty decent job getting down with minimal damage. The guy who saw it thinks the engine failed but I'd like to hear what the pilot says about it.The last video on this link is a security cam. Very narrow view but you can see a car swerve but still being hit by the wing

Looks to me like pilot brought plane down with minimum speed/momentum.
Something I love to see. Crumpled wings with an intact fuselage. Lets hear it for welded steel.
