Also lacks advice on HOW to fall:
New bike: Do your best to twist in mid-air so that you land on your back with bike held up in the air and free of scratches and dings.
Old bike: Try your hardest to kick the thing away as hard as you can so you can twist and land cat-like!
Pretty good article, though, and seems to have been put together by people who've thought in detail about the teaching and learning process.
