The aircraft is a Piper PA-32.
Just would like to add that I live in Hoboken for much of the year. I witnessed the US airways incident immediately after impact.
There is so much air traffic day and night up and down the Hudson. The angle at which some of those helos lift off is pretty remarkable.
I have a couple of theories of what happened but will wait for more information.
Just to add, I am not in Hoboken right now.
