Since we first considered here what didn’t happen to Malaysian Flight 370, there’s been a virtual flood of “theories” proposing what did.

The problem is, all of them start out with “it’s possible that” (rather than “the facts indicate”), from which a thinking person could only conclude what “might” have happened–with no better chance of knowing what actually did. Worse, once the boundaries are stretched to include “possible” and “might” as operative terms, you no longer have an investigation at all; rather, you have a piece of creative writing.

So much of what has been advanced as “theory” lately falls into that category, and those who are not airline flight operations insiders are most vulnerable to what is no doubt their good faith desire to find answers. But, with neither the technical background nor the aviation experience to separate what’s plausible from what isn’t, the results obscure the very truth they search for in the first place.

Malaysian authorities brief the press.

Let’s start with the most recent red herring “released” by Malaysian authorities–“the big left turn,” which supposedly “proves” that the turn was deliberately programmed into the flight computers, presumably by someone with nefarious intent.

In a word, that’s meaningless. There are just too many active and passive ways for “the big left turn” to be executed, even with no “programming” by what they insinuate was a rogue pilot. For example, look at the photo below:

The letters to the left are all navigation waypoints, composed of four or five character words representing geographic navigational fixes. Notice the waypoint “PROUD,” followed by the word “then,” which is atop the five empty boxes?

Below that, see the words, “Route Discontinuity?” That is the aircraft’s Flight Management System (FMS) telling me, the pilot, that I haven’t told it where to proceed after PROUD. In other words, there’s a break in the route and if I don’t fill those five empty boxes, the FMS will execute a big left turn (or right, depending on the shortest distance due to winds) and backtrack along the route to the points it came from.

And that’s just one possible, passive real time cause for “The Big Left Turn” so many theorists–including the Malaysian authorities and a news-starved press corps rushing to fill dead air–inexplicably point to as proof of some sort of deliberate, diabolical course programming.

Also, for some unfounded reason, the Malaysian authorities insist that “such a drastic turn could only be done by the autopilot coupled to the Flight Management System.”

Absolute nonsense. Daily, flight by flight I and hundreds of airline pilots hand fly all manner of climbs, descents and turns at all altitudes and speeds. That’s what we do.

Which brings me to the newest red herring that has the press panting and Malaysian authorities puffing up: the captain’s flight simulator video game. Supposedly, they’re going to search the game’s memory to see if the captain had “planned or practiced programming or flying” the Dreaded Big Left Turn.

Seriously? A captain with 18,000 flight hours needs to “practice” a left turn, or rehearse the FMS direct track to a waypoint? Which leads from the ridiculous to the absurd: no career pilot would need or want to “rehearse” a task that is on the level of an average person turning left into their own driveway. Even worse, accepting that the Malaysian authorities are investigating this as a serious clue is to accept that such a fundamentally meaningless red herring even bears investigation.

Once you do, it’s down the rabbit hole: “might” and “could” substitute for “did,” “assumptions” displace facts, which leads to conclusions that hold water like a sieve. Meanwhile, as the Malaysian authorities proffer useless leads, contradicting themselves with their own red herrings, inconsistencies and half truths–while the real investigative trail goes cold, and gets old.

What would motivate Malaysian authorities to divert public scrutiny to such empty yet showy “revelations?” Could it be to deflect attention from their top to bottom mishandling of the incident since the first minute: if, as the Malaysian authorities finally admitted, their military radar detected an unplanned, unauthorized penetration of their airspace by an uncommunicative jet at 35,000, why did the Malaysian Air Force not scramble fighters to intercept this very clear violation of their airspace and threat to their population at large?

If they had (yes, their Air Force has fighters and they are guided by the very radar that detected the straying airliner) no one today would be searching for Malaysian 370–because they would have followed it and determined their course and intentions.

It would seem less embarrassing for government and aviation authorities to paper over that glaring failure with sideshows like a crewmember’s flight simulator, or which pilot spoke last on the radio, or a mysterious Big Left Turn–which is probably why they’re doing exactly that.

And into the dead silence left by a complete lack of real evidence, come the voices of those who propose creative theories whose flames are fanned by social media with the nonsensical equivocation, “well, nothing else makes any more sense,” or “you can’t prove this didn’t happen.”

For example, some pundits propose there “might” have been a “fire,” which “could possibly” explain the transponder being “off.” Not “turned off,” in this scenario seemingly validated mostly by the way Hollywood portrays cockpit electrical failures: sparks, lights flicker out like in your house during a thunderstorm, then someone barks at a radio, “Ground control, come in please! Omigod–it’s dead!”

But a Boeing jet is not like your house, nor a Hollywood make-believe cockpit. There are multiple power sources and current routings, all designed to swap sources and even types of power to vital equipment–especially to communications and safety gear, including radios and firefighting systems.

And even if there were a fire, a turn toward land and an immediate descent with a mayday call is as instinctive to pilots as breathing and, in my Boeing jet–just like theirs–under most conditions I can set it up to perform the descent and level off safely even without me maintaining consciousness. That’s the way airliners are designed to fly, that’s the way professional pilots fly them.

And as my colleague Jeremy Giguere (he pilots The Big Kahuna, the Boeing-747) notes, Swissair 155 had a fire that destroyed the aircraft–but they talked with controllers for a full 15 minutes as they headed for land.

Fire? Sinister flight path reprogramming? All come under the venerable pilot term “WAG,” which translates to “Wild Ass Guess,” which is exactly what it sounds like.

So let me be clear: I don’t know what happened to Flight 370–and nor does anyone else. That’s because there are no facts from which to draw conclusions and until there are, I won’t attempt to wring fact from fiction.

To do so is to enter the Land of Oz where trees throw apples and winged monkeys dart about the sky, and Dreaded Big Left Turns plus Fire “possibilities” create a chaos that obscures what really ought to be a quiet, diligent search for facts and truth, when or if ever they are discovered.

Despite the shameful Malaysian bungling and the pointless social media circus following this puzzling tragedy, I believe in time the real facts will come out. Then a properly conducted investigation will yield a probable cause that will allow the aviation industry and flying community to make air travel safer.

The 200 lost souls and the loved ones they left behind deserve nothing less.
