Wow, how terrifying that must have been for those men, waiting to see whether they would be able to make a safe catch. Thinking about all the kids trying to catch a fly ball with their hearts fluttering, this one is the real deal.
No way to know, but the same thing happened here last week, unfortunately without somebody to catch the baby. It doesn't take long for an active todler to get somewhere they shouldn't be, and not all windows have kid proofing.
