Here's a quick take on the crash. Informed and conspiracy free, based upon the video:
Ship power cut off and the pilot panicked and threw engines into reverse (as seen by engine exhaust)
'Prop walk', which happen when you operate a propeller in reverse, turned the ship starboard into the bridge support
Some speculation in there about the state of mind of the pilot in trying to explain their actions. Hopefully the NTSB report will shed more light on things. The state of the steering particularly.
