Those 60 people in 2008 probably didn't either.
Hang on there just a cotton-pickin' minute..
We're not (and I'm most certainly not!) talking about scuba diving
- we're talking about cleaning someone's hull. I don't know many people at all whose boats draw more than around 8ft - and if they do, they can certainly afford to pay a professional diver to do it.
The posts I've made here are based solely on my own personal experience and not in any significant depth of water. As long as you're not stupid about this, yes, you simply, routinely, exhale when (frequently) coming up to the surface.. from 6 feet down. If you doubt me, go try it in a swimming pool.
From RFC 1925: "(3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead."
