(Web Desk) – Airplanes are the most swift way of travelling now a days and commuters prefer it for being luxurious and safe but there are enormous cases in past that revealed that air travel is not that safe as people presume.Here’s a brief description of 10 mysterious plane crashes that will leave you think twice before boarding a plane in  near future

Aer Lingus Flight 712

In 1968,61 passengers and crew on Aer Lingus 712 died while flying from Cork to London. An investigation into the crash revealed that an experimental British missile caused the devastation however this cause was dispelled later

Immediately after the crash, rescue efforts couldn’t find any wreckage.The majority of passengers were Irish, but there were a few Americans on board. The unique aspect of this crash is that, unlike most airlines which discontinue the use of crashed flight number, Aer Lingus still uses Flight 712 today.

TWA Flight 800

The third-deadliest aviation accident in US territory back in 1996 took 230 lives when a  plane exploded into a ball of fire and dropped into the Atlantic Ocean . Two separate investigations were triggered by the suspicion that there was criminal activity on the flight.

The FBI closed their investigation within 16 months citing not enough evidence, but itthe other investigative authority hinted that the highest probability of crash was a short circuit that triggered an explosion in the fuel tank. Investigators determined that there were no preflight faults and that a missile did not hit Flight 800.

Flying Tiger Flight 739

In 1962, the US military chartered Flying Tiger Flight 739 disappeared over the Philippine Sea after refuelling in Guam. There was no distress call, and the weather was sunny—it seemed the aircraft simply disappeared.Al 107 commuters died in the incident.

No remains of the flight weakened the investigative process and so no solid reason was identified of the disaster.

Pan AM Flight 7

The Flight 7 provided one of the luxurious air travel back in 1957 but on a route from California to huawei it got disappeared without leaving any trace.

Investigations raised eye brows of officials as it was suspected to be a case of insurance fraud or revenge.

USAir Flight 427

The 132 people who boarded USAir Flight 427 were expecting a short trip from Chicago to Pittsburgh. Sadly, within 10 minutes of their destination, the plane malfunctioned and dashed to the ground at a speed approaching 500 kilometers per hour. It was one of the deadliest crashes in US history.

Investigations that longed for four years found a  defect in the rudder caused the pilots to lose control.

Many of the victims’ families sued USAir Inc. and the Boeing Co. The two companies opted to settle out of court for nearly $50 million.

EgyptAir Flight 990

EgyptAir Flight 990 plunged into the Atlantic Ocean On Halloween Day of 1999,—killing all 217 aboard. The Egyptian Civil Aviation Authority (ECAA) investigated the crash along with american NTSB and both came to two different conclusions. The US determined that the copilot was suicidal and deliberately took down the plane. The Egyptians chalked the incident up to mechanical failures.some led to believe that it was a conspiracy against 33 members of the Egyptian General Staff who were on board.

The final exchanges on the flight’s voice recorder give us a pretty good idea. The pilot was recorded saying, “What is this? What is this? Did you shut the engines?” Meanwhile, the copilot was repeating, “I rely on God.”

United Airlines Flight 585

Similar to Flight 427, Flight 585 was the probable result of a malfunctioned rudder power control unit. The crash was shocking due to the history of the flight crew. Experienced pilots couldn’t resist the disaster that took 25 crew and passengers in 1991.

Flight 427 ivestigations played part into finding the cause of the disaster.Flight 585 crashed into Widefield Park at a reported 245 miles per hour.

Flight 19

The well known Bermuda Triangle mystery surfaced when Flight 19 began as a routine training mission for the US Navy, but ended in six planes vanishing into thin air and sparked the legend of the

The five Navy Avenger planes that made up Flight 19 started the mission on December 5, 1945. The weather was clear, and an experienced flight instructor was with the team. But 90 minutes into the exercise, the pilots became disoriented and couldn’t recognize the landmarks below.Strangely a rescue plane also went missing that night while hunting for Taylor’s team.

One of the most curious things about this incident is that a pilot  Taylor, asked to be excused from the day’s exercises. The Navy denied his request, and so he had to go with the unfortunate peers.

B47 Stratoget

B47 Stratoget which was carrying two nuclear weapon cores went missing in 1956.

Investigations revealed that the plane disappeared over mediterranean sea.United States dispelled any rumors regarding the unauthorized use of nuclear weapons that the plane was carrying.

Comair Flight 5191 (or Flight 191)

Thehorrific incident that took place in  2006 is believed to be caused by pilot error. The pilot strangely took a short runway instead of the conventional longer one that led to the disaster killing 49 people out of 50.

First Officer James Polehinke was the only survivor with severe injuries.Details revealed that the airport was not a state of the art piece using obsolete technologies and outdated maps.
