Specualtion that they pulled flaps up instead of gear up and basically didn't have enough lift so it looks like a gentle stall right into a built up area.

Looks to be flaps up, slats/ nose flaps down and gear down which is very odd.

And there's nothing in this preliminary report that would explain this loud bang during takeoff this lone survivor spoke of - it couldnt be the autostart of the APU when the main engines dropped out, and I suspect its not the RAT dropping out of its storage bay either.
Videos I see on YT where pilots flick these fuel cut off toggles on or off with hardly any effort must be the older version ( with no locking indent) that the FAA advised replacement?
Given the 737 max 8 cover up over those faulty angle of ascent sensors, and the fact that Boeing personnel are / were in the investigation team for this incident, I wouldnt give much credit to what is in this preliminary report.

The RAT was out before they left the end of the runway so pretty early. It does apparently make quite a big bang when it falls out into its position.

Here's what I find a little odd. Per the timeline, fuel switches are placed in Cutoff position, Pilot 1 identifies this immediately. Now TEN SECONDS elapse before Engine 1 switch is returned to Run, four more seconds before Engine 2 switch is returned to Run.

On the one hand, ten seconds doesn't seem like a long time, on the other hand it was ten seconds they didn't have. Makes me wonder what was going on on that flight deck.

EDIT: Pilot 1 & Pilot 2 hand fighting over the switches? If only there was video...

The report doesn't say "immediately ". The immediately thing was the engines started to spool down. Allowing 3 seconds for startle response, alarms starting to go off etc, it could easily take a few seconds of scanning of the cockpit before the other pilot said those words, then one of them moved the fuel levers back to on. Ten seconds in reality is pretty fast as I don't think the PF would see the actions they are concentrating on flying.

That's true, no time stamp associated with the CVR is reported. Surely one exists correlated with the FDR?

Even the old Jetstream with it's 8 channel cvr and 16 data recorder had a time stamp linking the 2. Think it was a tone pulse.

Common data bus linked to the FMS and GPS. GPS spoofing might cause problems I suppose.
