This Day in History Class is a production of I Heart
0:02
Radio. Hello
0:06
and welcome to This Day in History
0:08
Class, a show that shines
0:10
a light on the ups and downs
0:13
of everyday history. I'm
0:15
Gay Bluesier, and in this episode
0:18
we're talking about one of the scariest
0:20
close calls of the twentieth century,
0:22
the time when the U. S military
0:25
dropped an atomic bomb right
0:27
in one family's backyard. The
0:38
day was March eleventh, in
0:42
the Air Force b Fort Bomber
0:45
mistakenly dropped a nuclear weapon
0:47
on a rural farmhouse in mars
0:49
Bluff, South Carolina. The
0:52
bomb landed in the woods behind
0:54
the home of railroad conductor Walter
0:56
greg. He and his wife,
0:59
their three aldren, and a visiting
1:01
niece were injured in the blast, but
1:04
amazingly, they all survived.
1:07
Luckily, for the Greg's and for
1:09
the eastern half of the United States,
1:11
the nuclear bomb in question wasn't
1:14
carrying a radioactive payload
1:16
when it was dropped. By now,
1:18
you're probably wondering why the US
1:21
Air Force was flying a nuclear warhead
1:23
over South Carolina at
1:26
the time. The country was on high alert
1:28
for a potential nuclear attack from
1:30
the Soviet Union. To maintain
1:33
readiness and a moment's notice. The
1:35
military kept at least one nuclear
1:37
armed bomber in flight at all times.
1:41
On the afternoon of March eleven, the
1:43
BT responsible for the
1:45
Mars Bluff incident was in the middle
1:47
of one such training exercise.
1:50
It was called Operation snow
1:52
Flurry, and the mission was to
1:54
fly in atomic bomb on a practice
1:57
run from the Hunter Air Force Base
1:59
in Savannah, Georgia, to the United
2:01
Kingdom. Missions like this
2:04
obviously posed considerable danger
2:06
to civilians below, but the thread
2:08
of a Soviet strike made them worth
2:10
the risk, at least in the eyes of the military.
2:14
The crew of the B forty seven bomber
2:17
consisted of three men, the
2:19
pilot, Captain Carl M. Koehler,
2:21
the co pilot Captain Charles
2:24
S. Woodroffe, and the navigator, Captain
2:26
Bruce M. Kolka. Their
2:29
cargo that day was a twenty kiloton
2:32
Mark six nuclear weapon, and
2:34
even more powerful bomb than the
2:36
one dropped on Nagasaki. As
2:39
the plane flew over South Carolina,
2:41
a red fault light began to flash
2:44
in the cockpit. It indicated
2:46
that the locking pin on the bomb harness
2:48
was malfunctioning and would need to be relocked
2:51
manually. This was easier
2:53
said than done, as accessing the
2:55
cargo bay midflight required
2:58
the entire plane to be d pressure rised
3:00
and all of the airmen to put on oxygen
3:03
masks. The navigator,
3:05
twenty nine year old Bruce Kolka, was
3:07
sent to check out the problem, but he
3:09
didn't actually know where the locking
3:12
pin was located on the bomb harness.
3:14
He thought it might be near the top of the structure,
3:17
so he grabbed ahold of the harness and pulled
3:19
himself up onto the bomb. Unfortunately,
3:23
the handhold that Colca happened
3:25
to grasp turned out to be the emergency
3:28
release lever. He watched
3:30
in terror as the massive bomb
3:32
beneath him dropped from its harness
3:35
and collided with the closed doors
3:37
in the floor of the plane. For
3:39
a brief, tense moment, nothing
3:42
happened, and Colka just sat there
3:45
straddling a three ton bomb in
3:47
a scene straight out of Doctor Strange
3:49
Love. Then
3:59
all of a sudden, the bombay
4:01
doors gave way. Kulka
4:04
was able to scramble free in time,
4:06
but there was no stopping the bomb. It
4:09
plunged more than fifteen thousand
4:11
feet, landing almost directly
4:13
on a children's playhouse in the
4:15
Gregg family's backyard garden. It's
4:18
unclear why the accident didn't result
4:21
in a nuclear explosion. The
4:23
Air Force later claimed there was never
4:25
any danger of an atomic blast,
4:28
seemingly implying that the bomb's plutonium
4:30
core had been stored separately in
4:33
a different part of the plane. The
4:35
other option is that the payload was
4:37
indeed loaded into the bomb and
4:39
that had just failed to detonate, a
4:42
frightening prospect and not one
4:44
the military would be likely to admit even
4:46
if it were true. In either
4:48
case, the bomb may not have been
4:50
armed with a fission core, but it
4:53
was still packed with more than six thousand
4:55
pounds of conventional explosives.
4:58
The resulting blast flat nearby
5:00
trees, totaled both of the family's
5:03
vehicles and destroyed their house, which
5:05
stood just about a hundred yards away
5:08
from where the bomb had landed. The
5:10
force of its impact turned Greg's
5:12
garden into a massive muddy
5:15
crater, one that measured roughly
5:17
twenty five ft deep and over
5:19
fifty feet wide. Witnesses
5:22
later reported a mushroom cloud of
5:24
dust and debris that could be seen in
5:26
the sky from miles around in
5:28
all directions. The
5:31
entire Gregg family was home when
5:33
the bomb went off around four thirty pm.
5:36
They felt the house fall off its
5:38
foundation and watched as gaping
5:40
holes opened in the roof and walls.
5:44
Despite the wide scale destruction,
5:46
Walter and his family sustained only
5:48
minor injuries, and the only fatalities
5:51
that day were a few free range
5:53
chickens. Walter Gregg
5:55
remained remarkably upbeat about
5:57
his family's near death experience. After
6:00
being assured that the military would cover
6:02
all the damages, Gregg jokingly
6:05
said, quote, I've always wanted
6:07
a swimming pool, and now I've got a hole
6:09
for one at no cost. It's
6:12
worth noting, though, that Walter Gregg
6:15
was reportedly awarded just thirty six
6:17
thousand dollars, which wasn't
6:19
enough to rebuild his house or replace
6:22
his family's lost possessions.
6:24
On the somewhat bright side, the Gregg
6:26
family later appeared on the game show I've
6:29
Got a Secret And Wouldn't you Know It?
6:31
No one on the panel was able to guess
6:33
that an atomic bomb had fallen
6:35
in their back yard. Within
6:37
a few hours of the Mars Bluff incident,
6:40
Air Force police set up a two
6:42
mile perimeter around the blast site.
6:45
They also informed the local press that
6:47
the community was in no danger of radioactive
6:50
exposure, saying, quote, there
6:52
was not enough radioactivity present to
6:54
make a Geiger counter click. As
6:57
for the three man crew of the B forty
7:00
seven, they were hastily reassigned
7:02
to an overseas mission for the next
7:04
several years. It's
7:06
upsetting to think about military officers
7:09
fumbling a nuclear weapon, which
7:11
is why it's tempting to assume it was a one
7:14
time mistake. However, unplanned
7:17
bomb drops were in all too common
7:19
occurrence during the Cold War era.
7:22
The lost bombs that fell during
7:24
these unscheduled drops were
7:26
nicknamed broken arrows, and
7:29
more than a dozen of them were recorded throughout
7:31
the nineteen fifties and nineteen sixties.
7:33
In fact, less than three years
7:36
after the close call in Mars Bluff,
7:39
another nuclear weapon was dropped
7:41
by accident, just one stayed
7:43
over in Goldsboro, North Carolina.
7:47
In that incident, a B fifty
7:49
two bomber malfunctioned in mid air,
7:52
releasing two hydrogen bombs
7:54
on an unsuspecting community.
7:56
It proved to be another instance of
7:58
exceedingly good luck, as
8:00
neither bomb detonated, although
8:03
one came unnervingly close.
8:06
There's still a lot the public doesn't know about
8:08
these nuclear near misses, including
8:11
the true number that occurred. One
8:14
way to potentially get to the bottom of it
8:16
could be to go around and count
8:18
the craters, because, at least in
8:20
the case of the Mars Bluff incident, the
8:22
crater was never filled in. It's
8:25
severely overgrown, but it's still
8:27
there, just off South Carolina
8:29
Highway seventy six. There's
8:31
a historical marker and access sign
8:34
posted at the impact site, but
8:36
it is on private property, so visitors
8:39
should still ask the current owners for permission
8:41
before checking it out. After
8:43
you've had your fill of staring at a hole in
8:45
the ground, you can head over to the Florence
8:48
County Museum, where several bomb
8:50
fragments from the incident are still on
8:52
display. The shrapnel
8:54
was generously donated by the Gregg
8:56
family, who apparently preferred
8:59
not to have souvenir to remember
9:01
the day by. I can't imagine
9:03
why not. I'm
9:06
gay, Bluesier, and hopefully
9:08
you now know a little more about history
9:11
today than you did yesterday.
9:14
Before we close the show, I have an important
9:16
announcement to make effective
9:18
today. The show is moving to a five
9:21
episode per week schedule. That
9:23
means there won't be any new episodes
9:25
for Saturday's or Sunday's for
9:27
the foreseeable future. It
9:29
wasn't a decision we made lightly, but
9:32
for the sake of a healthy work life balance,
9:34
it's a necessary change. That's
9:37
because it's just me and Chandler making
9:39
the show, and delivering a new episode
9:41
every day of the year is a tall
9:44
order for just two people, so
9:46
in the name of quality over quantity,
9:48
we're gonna keep this a strictly weekday
9:50
affair for the time being. The
9:53
upside is that with a lighter load to bear,
9:55
we'll be able to keep making new episodes
9:58
of the show for years to come, so
10:00
stick with us as
10:02
always. You can keep up with the show by
10:04
following us on Twitter, Facebook, and
10:06
Instagram at t d I HC
10:09
Show, and if you have any comments,
10:11
concerns, or suggestions, feel
10:13
free to send them my way at this day
10:16
at I heart media dot com.
10:19
Thanks to Chandler Mays for producing the show,
10:21
and thanks to you for listening. I'll
10:24
see you back here again soon for another
10:26
day in History Class.
