Not many choices for the poor guy..
If the poor fellow was at 900' coming over the GW bridge and gliding, he couldn't make Teteboro, Westchester or Newark. He only had 2 choices...The NJ Turnpike or the river. Neither choice jumps off the page as preferable.
That's a major issue with LGA. It's surrounded by Queens, Brooklyn, Manhattan etc and if the you know what hits the fan like it did today, your options are extremely limited at best.
These guys really earned their pay today. An absolute miracle that no fatalities occured.
