In addition to billions of dollars in US Naval hardware on site were divers that brought their transports and equipment with them.
I imagine you are referring to the bottom of the luggage compartment fitted to the undercarriage, which was torn off the aircraft when it hit the water...and that's why we see a suitcase floating near one the passengers. As none of them left the aircraft carrying a suitcase, this suggests the luggage came out of the damaged luggage compartment. You choose to interpret this as some sort of flotation device. Just as you choose to portray the exhaust system floating above the engine compartment as mystery personnel, although one can clearly see the steam rising from the still hot engine in another image.
I was going to illustrate my comment with images that I had saved, but frankly, this game is too juvenile to bother. Please don't include me in your pings to this subject in future, the sheer stupidity is beyond my endurance.
No, I'm not referring to the bottom of the baggage pod, which was never seen to be floating alongside the plane.
You are right to note that none of the passengers was carrying a suitcase--or a purse.
What you call the exhaust system was not. The engine would have completely cooled to the surrounding water temperature in just a few minutes. We have a picture from roughly that time frame, and there's no grand water-heating event, even then. (The exhaust system is along the lower edge, horizontally in the following underwater picture.)
The picture you put in your post was taken roughly 35 minutes after the ditching, even though its video time stamp is closer to the 8 minute mark. No spewing bubbles at that point would have been coming from a hot engine.
Given the preponderant evidence of out-of-place electronics on scene, however, the one curiously-patterned (black with yellow stripes) luggage which would unfold for several minutes without any effort on the part of the passengers, to transform itself into an entirely submerged, unconventional PFD with an antenna, whose tip this (trained) wearer would studiously work to keep above water, is so not out-of-place after all. Those undeniable pieces of electronic evidence really are sitting in the midst of a Deep State hoax with a budget only found among other black ops.
In normal life, one doesn't see the NTSB falsifying evidence in multiple ways, either. Neither does the FAA destroy evidence that policy would tell them in four ways they should have been preserving for 5 years.
To believe you poo-poo'ers and ridiculers who call this a juvenile exercise is to allow the Deep State to make slaves of all of us. That's not a normal response from your typical Conservative Patriot. (Oh, sure a Conservative wants to judge things on the merits, but we've seen all-too-many hoaxes and government manipulation by now.) By your actions, words, and denigrating speech ("juvenile," "sheer stupidity," "idiot," "sweetiebuns") you folks have been telling us who you are--someone who's OK with the Deep State turning us into their controllable slaves. You're someone who's pleased to see a weaponized NTSB take its place right alongside Lois Lerner's weaponized IRS. In that sense and only that sense, I believe you.
I've seen this material vetted material with many an aviation professional, current and past Navy Seals, multiple USMC pilots, and long-time Intelligence Community people. Nobody from any of those groups has responded with your, 4Zoltan's or HG's antics. Not one. I've had a senior FAA investigator and a former NTSB investigator in Charge each separately tell me that I should be up in front of a class of FAA/NTSB personnel training them with this in-depth material. It's clearly your heel-nipping responses that are out of place.
The baggage pod is made of fiberglass. You'll be able to see it was broken up, not breaking off in one nice, big flexible piece as we see along side the plane.
The baggage pod color is entirely different and could not be considered green in any lighting. There were internal fiberglass bulkheads every four foot or so. That's entirely different from the smooth, continuous green, unbroken Slipe-N-Slide (R) alongside the plane. (See bulkhead rivets to the left side of the following picture, on both side and bottom panels.)
The upper part of this following picture is the internal floor of the baggage pod, with the outer being painted white as was the rest of the plane.
It's unclear how you could have made that misidentification, except perhaps through wishful thinking.
All the rest of the baggage pod contents were strewn a good distance behind the plane as it came to a stop, as can be seen in the following picture.
It's beyond curious and coincidental that that one particular piece of baggage which would unfold and transformed itself into a lifejacket cum 20" phallic antenna, would just happen to be something one of the passengers (the passenger-author's wife), would wait 15 minutes for in the water without another life jacket. In had been doing that all that time in apparent noncompliance to the pilot's claimed instructions, which were that everyone should put on his PFD before exiting the plane, just to strap this one on after it had fully engorged itself with water.
Immediately after Fuddy is extracted from the situation, she all of a sudden has lost her phallic life jacket and now has an adult life jacket from the plane (She's on the right.).
Could that have been the adult life jacket taken from Fuddy, which Fuddy was seen to be wearing earlier in the scenario? No, but since Fuddy was said later said to be wearing an infant life jacket someone certainly should have been investigating that angle. But neither the Maui county police nor the FBI did!
