This is interesting, but sort of a head scratcher.
If the pilot wanted to ensure no debris, wouldn’t the simplest thing to do be to simply dive into the sea? Why glide in with gear down?

Aviation Inspector Turdgeson: He appears to have intentionally set the gear down prior to impact. We’re still trying to figure out the significance of that act.
President of Malaysia: There is nothing to figure out Inspector. The man was obviously a psychotic.
Inspector Turdgeson: Well sir, I’d like to hold off on making any judgments like that until all the facts are in. However, at this time it does appear that the human element has failed us.

You want the plane to remain intact, not in pieces, so you would land as gently as possible. The gear down might have been an attempt to make sure the plane would fill with water as quickly as possible.
Anyone know where the coax cables to the antennas run in a 777? I’m betting alongside the crew emergency oxygen bottle, under the cockpit, which blew up causing instant depress. Not meant to happen but it does. Happened to Qantas once. Explains sudden loss of comms, dive and turn towards emergency field to north which disconnects normal autopilot mode. Crew go unconscious shortly thereafter – likely 15 seconds max. Airplane zooms back up where pitch stability takes over and it settles at trimmed AoA. 777 autopilot “off” mode has a wing leveler (not heading or track hold) which is why no spiral dive. Airplane flightpath gets disturbed by flying through tops of cu nims in ITCZ, eventually hits a big one and gets spat out heading south, exiting ITCZ. Passengers and crew all dead at this point. Cabin crew with walk around bottles can’t get into flight deck due locked door. Eventually die.
Airplane runs out of fuel, wings level. RAT deploys, airplane glides into ocean flaps up at trimmed AoA, likely at around 250 KIAS which tears bits off the bottom of the airplane as it breaks up.
Theory from a former RAAF P-3 pilot who thinks flash fire may be the initial cause, mine is the oxy bottle.
Note airline sims DO NOT reproduce the wing leveler mode, Boeing’s iron bird does.
This theory gets you banned from the pprune website which I’m told Boeing owns a part of.
Pitch stability likely won’t bring it to a stable, constant AoA, unfortunately. Rather, the aircraft will follow a phugoid.
See United 232, JAL 123, DHL A300 over Baghdad.
Also known as “porpoising,” if I’m not mistaken?
Full-time fly-by-wire aircraft; I guarantee it has active phugoid damping (and if needed, stabilization) built into the inner loop.
The rest of the hypothesis…I have no opinion.
What ever happened to above a critical altitude, at least one pilot must be “on oxygen”? Or have one of those quick-bale oxygen mask thingies?
Gear down to deliberately rip it off and cause damage to the rest of the aircraft? Or to shut off the ‘Gear Warning’ alerts??
Mentally impaired and/or physically injured pilot following standard Runway landing checklist by learned reflex? Who knows…?
If that’s a piece of an airplane, there is a number, actually several different numbers, on it that traces directly to what airplane it came from. No need to decipher gashes and scratches.

Unless, of course, you want to figure out how it got from point A to point B.
