Natstrackalpha what if this was his only real way to go, couldn't do it any other way (slim chance I know) but if so maybe he thought briefly about the 143 people behind him and didn't want their final moments to be a full on dive.
I apologise if that adds nothing constructive or logical.
The one thing I do know about suicide (attempts) is that you generally don't think about the people you're going to affect by what you're doing. You have one goal and one goal only.
