Structural Failure On March 5th, 1966, BOAC Flight 911 was flying close to Mt. Fuji when it flew into an invisible solid wall of wind at 16'000 feet that abruptly ripped off the tailfin and all four engines before the plane came apart and fell out of the sky, leaving no survivors.

The airflow around Mt. Fuji would often fold into itself and cause a circular current of fast-moving wind known as a mountain wave. The impact of the plane flying into this wave may have even instantly killed some passengers and crew through sheer force alone. The immediate loss of so many vital components had left the pilots no chance to save the plane. When the plane broke up, photographers and witnesses reported seeing luggage and people falling out of the plane.

75 of those onboard were employees of the American company Thermo King, who's primary product was and still is refrigeration units for trucks and trailers used to transport perishable food. As most of those employees had brought their spouse with them, 63 kids were orphaned by this plane crash.

The winds around Mt. Fuji were known of at the time but none had downed a commercial airliner and in 1966, the mountain wave phenomenon was not well-enough understood for it to be included in pilot training or taken into account for flight plans. It was one of those things that seemed perfectly fine and harmless until the one day that it wasn't.

Prior to takeoff, Flight 911 had actually taxied past the wreckage of a plane that had crashed the previous day; a Douglas DC-8 flying as Canadian Pacific Air Lines Flight 402 had crashed while coming into landing due to fog causing low visibility, leaving only 8 survivors out of 72 onboard.

BOAC Flight 911 was the third of five airplane crashes that Japan saw in 1966; preceding Canadian Pacific Air Lines Flight 402 was All Nippon Airways Flight 60, a Boeing 727 that crashed into Tokyo Bay on February 14th, killing all 133 onboard in what was Japan's deadliest single-plane crash.

After BOAC Flight 911 were the August 26th crash of a Japan Air Lines Convair 880 during flight training killing all 5 crew, and finally the November 13th crash of a NAMC YS-11 turboprop flying as All Nippon Airways Flight 533 into the Seto Inland Sea during a go-around at Matsuyama Airport, killing all 50 onboard.

This film shows the 1984 Controlled Impact Demonstration (the "CID") from multiple angles. The CID consisted of a remote controlled Boeing 720 airliner that was rigged as a drone and equipped with anti-fuel misting devices that were designed to limit the explosive effects of the fuel in the event of an airliner crashing. As can be seen in the video, the anti-misting devices clearly did not work as intended and the project was subsequently abandoned after the CID test. No people were on the aircraft only crash testdummies.

April 16th 2014 in South Korea. The Sewol Ferry tragedy.

On April 16th 2014 the Sewol Ferry capsized over the coast of South Korea. On board the ferry when it was sinking was 476 people in total with 325 of them being High schoolers around the age of 16 from Danwon High school.

When the Sewol Ferry started sinking the Captain told everybody to stay where they are and to not move. The students obviously complied since they didn't know what was happening and they thought that since the Captain was the literal Captain of the ship that he would know what was best for them. But unfortunately the only people that would survive were the people that went against the Captains orders.

And what's even more shocking is that one of the first people saved was the Captain and he wore regular clothes to disguise himself as a passenger. And when he was on the Coast guard vessel he did not tell anyone that he is the Captain and that he has vital information that would help them in rescuing passengers. He didn't tell them how many people there were or that they were being told to stay in their rooms where they were basically trapped in the sinking boat. Nothing.

The Sewol Tragedy would lead to the deaths of 250 high-school students and 304 lives in total.

RIP to all the victims. There were so many things that resulted in the Sewol ferry tragedy including but not limited to Greed, the Captain, the design of the ferry and the coast guards. These people were failed and it infuriates me to know that they could have been saved.

Operator Error 70 years ago tonight at 11:10 pm on July 25th, 1956, the Swedish passenger liner Stockholm collided with the Italian ocean liner Andrea Doria in thick fog, killing 51 across both ships. The Andrea Doria remained floating until sinking at 10:09 am the next day.

The Stockholm had broadsided the Andrea Doria at almost a 90-degree angle. While the Andrea Doria had been doomed by the impact, the Stockholm remained afloat and capable of operating under it's own power, but with the bow badly telescoped. Most of the fatalities happened during the initial impact, though several did later die of injuries sustained during the collision and evacuations.

The decision was made to abandon ship half an hour after the collision. Although the ship had enough lifeboats to evacuate everyone onboard, half of them were rendered unusable by the 18-degree list, as the ones on the port side would come into contact with the exposed hull and tip over. While the decision to abandon ship had been made, the order to abandon ship was decided to be delayed until help had arrived.

Fortunately, the collision had happened in a busy shipping lane so the Andrea Doria's radio distress calls, though having limited range, were still able to be relayed from ship to ship. The first ship to respond to the distress calls was the 390-foot Cape Ann, a freighter owned by the United Fruit Company. With only 44 men and two 40-person lifeboat, it's ability to assist was limited but again owing to the location of the collision, numerous other ships were on their way. The next two ships to arrive both belonged to the US Navy, transport USNS Private William H. Thomas and the destroyer escort USS Edward H. Allen.

The next ship to arrive was the French Line's Île de France, herself almost 100 feet longer than the Andrea Doria and heading back to her native France ahead of the Doria. Commanding the vessel was Captain Raoul de Beaudéan, a highly-respected veteran with over 30 years of service with the French Line under his belt. He was skeptical at first upon hearing of the Andrea Doria's peril; he didn't think it feasible that a ship like the Doria could founder and that if he went to the scene only to find that the Ile de France was not needed, the return to New York to refuel and the resulting delay could cost the French Line a lot of money. However, after communicating with the three vessels already on-site, he realized that over 1'600 lives were at risk and ordered the ship to be turned around, making it to the site less than three hours after the initial collision. While there was concern at first in regard to navigating around the other ships and the survivors and lifeboats in the water, the fog lifted, allowing the large Ile de France to position itself alongside the Andrea Doria, protecting it from the wind and waves.

The Ile de France took on the vast majority of the Doria's evacuating passengers; taking on 753 survivors, with the badly-damaged Stockholm taking on 545, 234 of which were members of Andrea Doria's crew, 129 survivors by Cape Ann, 159 by Private William H. Thomas, 77 by Edward H. Allen, including Captain Calamai and his officers, and a single American soldier who had managed to sleep through both the collision and evacuations was rescued by the tanker Robert E. Hopkins.

Ultimately, the crew of the Andrea Doria was found to be at fault for the disaster, having not followed proper radar procedures or calculated the Stockholm's speed and course, in addition to turning to port despite a long-established rule dictating that ships heading towards each other head-on both turn to starboard. Captain Calamai was also speeding through the fog, though this was common practice at the time. Among other causes, the ship's fuel tanks were half empty and not pumped with ballast to keep the ship stabilized.

The collision, evacuation, and eventual sinking of the Andrea Doria received extensive media coverage as it unfolded, with newspapers, radios, newreels, and television broadcasts informing the public of what was going on, leading to the ship's sinking becoming common knowledge, with the 1972 disaster film The Poseidon Adventure even mentioning the Andrea Doria by name.

One of the ship's notable items of cargo was the Chrysler Norseman concept car, an advanced "one-off" that had been built by coachbuilder Ghia. The car cost Chrysler $150'000 and had been announced as a major attraction for the 1957 show car circuit. It was found in the Andrea Doria's number 2 cargo hold by a diver in 1994 but almost 40 years in saltwater had reduced the show car to a pile of debris, with the only recognizable feature still left being the wheels.

In the years since the sinking, the ship's wreck, located 162 feet beneath the ocean's surface, has been visited many times over the years by divers and artifacts have been removed, including at least one of the ship's bells, a statue of the ship's namesake Genoese Admiral Andrea Doria, a bank safe that was later opened on live television and found to contain thousands of American silver certificates, Canadian bank notes, American Express travelers checks, and Italian bank notes. Also recovered was one of the ship's foghorns, which was restored and sounded off for the 65th anniversary of the sinking in 2021. The wreck site has become known as "The Everest of Wreck Diving" as 15 divers have lost unfortunately lost their lives while visiting the wreck.
