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.
