Interesting. How does bird strike on one engine shut down all systems? Aren't there a left/right engine system and an auxillary? The same video was updated today, and he conjectured it may have been they shut the wrong engine down like in a previous Taiwan air incident. They only had 5 min. to do anything according to the timeline.
A bird strike doesn't. From the external video, none of this makes sense. The hydraulics are triple redundant and independent of each other. Even without both engines to run pumps or generators, you can drop the gear via gravity and use either leftover hydraulic pressure to drop flaps or the use electrical backup, which should work on battery or APU.
You can hear at least one engine running before it touches the ground AND you can see that the plane is at least in somewhat in control, considering it lines up with the runway properly and does a flare AND a thrust reverser is active before it hits the ground.
The control surfaces work without power (with great effort) since they are mechanically linked in the case of emergency on the 737 NG. If the gears were down, it should have triggered automatic flaps to slow the plane down on touchdown.
None of this makes sense, unless we assume the pilots royally fucked up basically everything. They missed the optimal landing point and only used about 40% of the runway traveling at what appears to be at least 80 knots above the normal max landing speed.
