This is not my normal blog post. It may be moot at any time, but it is a relevant question anyway.
The disappearance of Flight MH370 has led to wild speculation by the media based on little or no evidence. I believe there are some basic questions that have not been answered:
- Why did the ELT fail to activate? Why were there no distress calls from the aircraft?
- What happened to the pings to Inmarsat between 1:07 and 08:11?
- Why is the arc for the location of MH370 truncated between Vietnam and Indonesia? What makes this area exceptional?
- What is the time it takes a 777 flying at normal cruising speed to turn 300°?
- Was the "unknown aircraft" that we assume to be MH370 really it? Were there any other "unknown aircraft" in the sky that night?
- What is the maximum limits of the radar observations of the "unknown aircraft?" Does it terminate in the Malacca straits? On the Andaman islands? Beyond?
- In the court of Occam's razor, do eyewitnesses count for anything?
- Do eyewitness accounts tie in with the known facts?
- What would cause radar echoes to be intermittent?
I ask these questions as a layman, I have no special knowledge or skills. In doing so I am going to apply Occam's razor (i.e. Make no more assumptions than is necessary).
I will use the word "allegedly" a few times in this post. This word means 'I have no corroboration' for the facts stated. It does not mean "I am suspicious."
Here are the sequence of known, relevant events:
- On 8 March at 00:30, MH370, a Boeing 777, departed Kuala Lampur with 227 passengers and 12 staff on board. The weather was normal.
- Two of the passengers on board were travelling under false passports. They have allegedly since been cleared.
- At 1:07 the last ACARS transmission is made. The next transmission is expected in either 30 minutes or 1 hour. It is unclear from the reporting whether the satellite or plane initiates this request.
- At 01:19 MH370 sent it's last transmission to Malaysia Air traffic control saying "All right, good night." This is the last intelligible vocal communication.
- At 01:21 MH370 disappeared from radar. This is the last known radar contact with MH370.
- At 01:28 Thai radar picked up an unknown aircraft flying in the opposite direction to MH370 in the same vicinity as MH370. This aircraft's signal was intermittent.
- Malaysian radar also picked up an unidentified aircraft in the same vicinity, although times are not given.
- This aircraft is assumed to be MH370.
- At "just after 01:30" the pilot of another aircraft makes contact with MH370. He hears static and "mumbles". This is the last known verbal contact with MH370.
- While on this course, the unidentified aircraft allegedly makes a series of erratic altitude changes. It goes up to 45000ft (above the safe operating limit for MH370) down to 23000ft (below normal cruising altitude for MH370) and then down to 5000ft.
- This aircraft travels south west into the Malacca Strait. Based on some reporting the aircraft followed commercial airline waypoints.
- The narratives now diverge:
- According to Malaysian authorities the aircraft follows a complex set of navigation points to eventually take a route that would lead it to Europe, crossing the Andaman Islands.
- According to Thai reports the aircraft turns left into the Malacca strait and then makes a right turn towards Butterworth, Malaysia.
- At 08:11, Inmarsat reports a "ping" response from MH370, response times indicate a possible arc of the current location. No intervening pings are given. The centre of the arc defined by this ping is excluded as possible locations, even though it intersects the original flight path of MH370. Reports differ as to whether the plane needed to be in the air for this ping to occur.
- The Emergency Location Transmitter (ELT) did not activate. At 01:19, 08:11 or at any time in between.
- No mayday signal was sent by the crew.
The most convincing eyewitness account I have seen is from Mike McKay. His observations are detailed in every way except that he did not quote a time. Other than that, Mike would be my primary source. His account was early, precise and detailed. Tie that to an aircraft flying at 45000ft instead of 30000ft and the numbers start to add up.
Other eyewitness accounts:
- Fishermen in the Malacca straits find a life raft with the word "boarding" on it.
- Fishermen report seeing an aircraft fall in the Malacca straits. Wrong date, wrong time. However, the description is seems to mesh with a catastrophic failure.
- Fishermen off the coast of Andhra Pradesh report "bits of something." I admire the reserve.
- Reported sighting over the Maldives, flying North to South East at 06:15 local time. These guys were definitely hungover (or the US guys at Deigo Garcia were messing with them.) The numbers do not compute.
Theory 1: MH370 suffered a catastrophic failure between 01:21 and 01:28. To purport that a commercial aircraft can lose all signal in 7 minutes due to human intervention is reaching.
Theory 2: MH370 crashed somewhere off the coast of Vietnam due to theory 1. If the Inmarsat beacon somehow stayed alive, it would explain the ongoing responses.
Theory 3: MH 370 crashed somewhere between the Andaman Straits and the Indian coast. This would assume that the Anmarsat responses were not absolute, but would explain three of the eyewitness accounts. I dedicate this theory to Courtney Love with no irony whatsoever.
Theory 4: The aircraft crashed somewhere between the Malacca straits and the Indian coast. This would explain two eyewitness accounts and match the last assumed direction of the unidentified aircraft. It would question the Inmarsat locations.
Theory 5: The aircraft continued flying and crashed or landed somewhere else on the Inmarsat arc or 30 minutes beyond. This calls into question all of the known facts except the Inmarsat pings.
Theory 6: Whatever the truth is discovered to be.
As much as this is a curious mental exercise, I do acknowledge that real people are involved. The missing, their families, the bleeding hearts and artists. Ordinary people. I do care, in my way.
Lastly I want to say to all the media: Your ugliness has been noted.
