## **1. MH370 and the Mysterious Disappearance**
– **On March 8, 2014**, Malaysia Airlines flight MH370, carrying 239 people from Kuala Lumpur to Beijing, disappeared from radar after only about an hour of flying.
– At 1:19 a.m., Captain Zaharie Ahmad Shah sent his final message: **”Good night, Malaysia 370″**.
– Just 2 minutes later, the transponder was turned off, causing the plane to disappear from civilian radar systems.
## **2. Unusual Turns**
– MH370 then appeared on military radar, showing that it had **abruptly turned** west, flying over the Malaysian peninsula.
– The plane continued flying along the Strait of Malacca, then turned south towards the Indian Ocean. – The final data from the Inmarsat satellite indicates that it flew for about 6 hours before losing contact completely.
## **3. Satellite Data – The Only Clue**
– Because the transponder was turned off, MH370 could not contact air traffic control, but it still sent **7 “handshake” signals** to the Inmarsat satellite.
– From there, scientists calculated the flight trajectory of MH370 by analyzing:
– **Doppler effect** (shift in signal frequency)
– **Signal delay** (time for the signal to travel from the plane to the satellite)
– The results showed that MH370 flew south, to a remote location in the **Southern Indian Ocean**, where no commercial flights pass.
**4. Why Did the Plane Disappear? – Main Hypothesis**
### **4.1. Deliberate Action**
– Aviation experts, including former pilots and investigators, suspect that **Captain Zaharie Ahmad Shah** deliberately steered the plane away from the ocean.
– Some evidence:
– The flight path was complex, seemingly controlled manually.
– The communications system was deliberately turned off.
– The plane may have made a final turn before crashing.
– However, the motive behind this action remains a mystery.
### **4.2. Mechanical Failure?**
– Some other theories suggest that there may have been a loss of cabin pressure, causing the crew to lose consciousness and the plane to continue flying until it ran out of fuel.
– But if it was an accident, why didn’t the emergency beacon (ELT) system work?
## **5. Previous Search Efforts**
– **2014 – 2017**: Australia, Malaysia and China led the search, using autonomous submarines to scan the seabed.
– **2018**: Private company Ocean Infinity joined the search with more advanced technology, but still failed to find the plane.
– **Debris**: Some debris from MH370 washed up on the shores of Africa and Réunion Island, confirming that the plane crashed in the southern Indian Ocean.
## **6. New Technology – Hope to Find MH370**
### **6.1. WSPR Method – Long Range Radar**
– Scientists are using the **WSPR (Weak Signal Propagation Reporter)** system to track MH370.
– WSPR is a global network that monitors long-range radio signals. When planes fly over, they can cause interference in this system. – Data from WSPR helps determine more accurately the final flight path of MH370.
### **6.2. Ocean Infinity – Seabed Scanning Technology**
– Ocean Infinity uses **unmanned underwater vehicles (AUVs)** that can dive much deeper and scan much wider than previous searches.
– They propose a new search in 2024 under a “no find, no fee” contract.
## **7. Why is the Search for MH370 Important?**
– **Families of the victims**: After 11 years, relatives of the 239 passengers still want to know the truth.
– **Lessons for the aviation industry**: Finding MH370 could help prevent similar disappearances in the future. – **Decoding the greatest aviation mystery of the 21st century**: If the plane wreckage is found, the black box could help answer the question: **What really happened to MH370?**
After 11 years of disappearance, an Australian expert claims to have found signs of the crash site of flight MH370 at the bottom of the Indian Ocean. The suspected location is at coordinates 33°2′ South, 100°27′ East, in a crater in the Broken Ridge underwater mountain range. The discovery raises new hope for the search for the Malaysia Airlines Boeing 777 that went missing in 2014.
