If our speculations about a too-wide turn are indeed correct, it might point
to the need for additional training on that issue (although even on the East
River--which is about the tightest turn I know of that a pilot would
ordinarily need to make other than in mountain flying--I'm not aware of any
other crashes caused by the tight turn).

Well a lot of people drop it in making too tight base-to-final turns.
Balling it up on the ground just doesn't make the news like hitting
a building in the process.
