another scenario.

for crew migration

possibly destabilizing

the aircraft in flight,
leading to a crash.

narrator: If the crew suddenly
switched positions,

the center of gravity
for the aircraft

the ship that reported

an aerial explosion
may have actually

been seeing the aircraft
impacting upon the water

narrator:
But what would cause the crew

to shift position so rapidly?

Jason thinks this may connect
to the team's theory

about a close call

- And it's possible
that the pilot

could have made
an evasive maneuver.

And at that point,
it's potential that

crew members
could have come forward,

not by their own doing,

and this one up here
is the actual engine.

But there's scattered bait all
throughout this whole thing.

So there's obviously
more metal that's...

narrator: Mickey's bottom
sonar is picking up

potential wreckage the team

didn't see
on their first dive.

- What's the overall distance
from north and south?

How big of an area are
we talking about here?

- 240 feet.

narrator: As Mike and Jimmy
prepare to splash in

to see if they can tie this
engine to the Martin Mariner,

back on land, Wayne and David
get the phone call

they've been waiting for.

- Oh, very good.
Dave's here as well.

- How are you doing, Nate?

- Good.

narrator: Wayne and David
suspect an aircraft wreck

found in a swamp to be from
a TBM Avenger torpedo bomber,

possibly part of Flight 19,
the very planes

the Martin Mariner was trying
to search for

and rescue in December 1945.

Their initial analysis
of the wreck

indicated the parts
were a match

for a Curtiss-Wright engine,

the same used
by the lost planes.

Researcher Nate Ingram
has an update.

- Any luck?

- Wildcat?

I thought they only used
Pratt & Whitney's?

- Really?

narrator: Curtiss-Wright did
build the Avenger's engine.

But they also built an engine
for a smaller plane

called the FM-2 Wildcat.

- Very disappointing
to find out

that the wreckage that
we found in the swamp

is a Wildcat
and not an Avenger.

And on top of it, it doesn't
prove John Myhre's theory.

We knew it was a long shot at
best, searching in the swamp.

But I felt that we needed
to take the shot.

narrator: The swamp wreck
didn't prove

that Flight 19 had a close
call with the Martin Mariner.

But it sure seems
like something did.

For now, the mystery
of the second radar blip

remains unsolved.

But 45 miles offshore,
Mike and Jimmy are hoping

that they'll
find the Martin Mariner

and answer once and for all
how and why she crashed.

again, a challenge.

- On the bottom,

maybe 15 feet.

narrator:
Then a shape appears.

It's a large piece
of wreckage the team

didn't see
on their first dive.

- So we get down there.
We find this wing.

narrator: Any aircraft wreck
is a potential grave site.

The team must proceed
with great care.

So they decide to use a
process called photogrammetry.

Jimmy circles the wreckage,

taking hundreds
of still photos.

He'll process these images
to create

a 3D model of the
wreck site that allows

a more in-depth analysis.

- There's only part
of a wing here,

and obviously,
it's pretty degraded,

so it's clearly been
in the water a long time.

narrator:
Then another potential clue...

an unusual structure
lies near the wing.

an unusual structure

But what is it?

[dramatic music]

narrator:
45 miles off the coast

of Central Florida...

narrator: Mike and Jimmy
have discovered tantalizing

new pieces
of an aircraft wreck

they suspect to be the
Martin Mariner rescue plane.

- It's important
to find Training 49.

It's a huge Bermuda Triangle
mystery,

and we wanna put closure
to that.

narrator:
The team has already located

an 18-cylinder aircraft engine

and a piece of the wing.

Mike swims a larger perimeter

Any other wreckage remains
buried in the sand.

- Where are the two pieces?

- Not far.

- Like 50 feet?
- 50 feet, yeah, yeah.

We were able to swim
from one to another.

Then I went back to the wing.

- It's definitely
a section of wing.

narrator:
More clues are pointing

toward the Martin Mariner.

But a grizzled wreck hunter
like Mike Barnette

needs firmer evidence.

- We don't have a smoking gun.

We don't know what aircraft
this engine went to.

We can't rule out
the Martin Mariner,

so it's gonna take
a little bit more work.

narrator: One thing
is becoming clearer.

The wing has
military grade features.

This is a military aircraft.

That means permission
from the navy is needed

for a more
intensive excavation.

- We know
there's other material

that has to be there somewhere,
most likely buried.

Hopefully we can
reach out to the navy,

get some assistance from them.

narrator: Mike begins
the long process of seeking

the navy's official permission

for a fuller excavation
of the site.

But the team does have
one last shot

to make an ID
with evidence in hand...

Jimmy's 3D model.

It may reveal a key detail
that Mike and Jimmy missed

on their visual inspection.

♪ ♪

- Let me start out
with the wing.

♪ ♪

About 100 to 150 feet
to the south of where

we had started
on that engine site.

- 100 feet from the engine?

- Very close.

- Yeah,
but definitely scattered.

- Exposed, I'd say
about 10 to 15 feet.

narrator: Then Jason Harris
spots something in the model.

- I'm really wondering
what this piece of material

is right there.

'Cause it, like,
has a perfectly round shape

in the center.

narrator: To Jason,
this could be the remains

of a fuel bladder.

If so, that would be a major
tell for the Martin Mariner.

It had both
an 18-cylinder radial engine

and a fuel bladder
in the wing.

♪ ♪

And Jason sees more clues
in the shape of the wing.

- This area here,
that looks like

it's kind of the edges
of the wings.

- I do have a few photos
of the Martin Mariner.

Now, when you look at this
wing, Jason, what do you think?

♪ ♪

- Look at the wing.
It's rounded.

- Yeah.
- It's a rounded wing.

- I cannot say
definitively that

this aircraft wing structure
belongs to a Martin Mariner.

What I can say is that
there is a possibility,

because the wing structure
is rounded,

similar to the diagram
of a Martin Mariner.

And it has a rounded
wing structure.

narrator:
The 18-cylinder engine,

the potential fuel bladder,

and the rounded wing
are all features

of the missing rescue plane.

But Jason, Dave, and Wayne
agree with Mike Barnett.

There simply isn't enough
to make a definitive call.

- So is it possible? Yeah.

- Wow.
- But...

- We don't have
enough to confirm,

but we can't rule out, either.

narrator: It's been a
whirlwind of an investigation.

The team has broken new ground
on a provocative theory,

and the mysterious radar blip
demands further investigation.

- But that's how
you do research.

You pose hypotheses.
You test those hypotheses.

And at the end of the day,
some of them may hold water,

some of them may not.

And that's the one thing
with the Flight 19 mystery

and the Martin Mariner.

There's just so much more data
to be discovered.

narrator: And there's
more work to be done

exploring Mickey's Wreck.

- I mean, this site
bears watching,

because if we have a hurricane
come through here,

it could uncover
a bunch of other wreckage.

So if we can't get
permission from the navy,

maybe Mother Nature
can help us.

We would love for this
to be a one-off dive,

go down,
find the Martin Mariner.

But we've been at this
long enough to realize

this is gonna be a slow,
steady just struggle.

We're gonna get to a point
where the last site

we dive is gonna be
the Martin Mariner.

And that's what they
always say, right?

It's always
the last place you look.
