I have to agree with your comments here. I honestly don't know what I would actually do in a similar situation, but I think that the safest bet would have been to stay on the ground here...at least you know what you have when you are on the ground, and the crash crew is very near-by in case things go badly. Taking an aircraft with unknown damage into the air is not the best option in my mind. What happens if there is structural damage severe enough to cause inability to fly issues at 6000 feet after the go-around? A lawn dart crash is going to be far less survivable than a belly landing. I wasn't there, and I applaud the crew for bringing it back safely, but in the end, even though it all worked out, it doesn't necessarliy mean that it was the safest call.
