Hobby pilot and aviation enthusiast Keith Ledgerwood, is one of the many millions pondering the disappearance of Malaysian Airlines flight 370, as it drags on into the 10th day, with a twist, he has a plausible story about how it could realistically have eluded radars.
As the story has turned transcendent, becoming, from a story about an airplane crash, a mystery story, Mr Ledgerwood did a bit of researching after he noted that the major roadblock to the theory that the airplane could be on the ground anywhere along a path from northern Thailand to the border of Kazakhstan and Turkmenistan has been the insistence from India and Pakistan that their radar network showed no such unidentified aircraft entering or traversing their airspace.
As he noted,it would seem highly unlikely given such information that a Boeing 777 could indeed slip through undetected.
So he started plotting the available data up to airplane's disappearance. He began by plotting the course of MH370 onto an aviation IFR map which shows the airways and waypoints used to navigate the skies. He plotted the point where it stopped transmitting ADS-B information at 1621UTC, and then plotted the Malaysian military radar track from that point towards “VAMPI”, “GIVAL”, and then onward toward “IGREX” on P628 ending with where the plane should have been at 1715UTC when military radar lost contact.
He then looked at what other planes were in the air at 1715UTC, their positions and courses, and saw something, at first odd looking, another Boeing 777 was en-route from Singapore over the Andaman Sea. He then plotted the exact coordinates of Singapore Airlines flight number 68’s location at 1715UTC onto the aviation map and realized that SIA68 was in the immediate vicinity as the missing MH370 flight at precisely the same time. Furthermore, SIA68 was en-route on a heading towards the same IGREX waypoint on airway P628 that the Malaysian military radar had shown MH370 headed towards at precisely the same time.
As he inspected SIA68’s flight path history it became apparent that MH370 had maneuvered itself directly behind SIA68 at approximately 17:00UTC and over the next 15 minutes had been following SIA68.
As Keith Ledgerwood became perturbed, he noted that Singapore Airlines Flight 68 proceeded across the Andaman Sea into the Bay of Bengal and finally into India’s airspace. From there it appears to have proceeded across India, Pakistan, Afghanistan, and finally Turkmenistan before proceeding onward across Europe to its final destination of Barcelona, Spain.
Mr Ledgerwood provided the map depicting the approximate flight path of SIA flight 68 on that particular day, noting that additional detail will be required from each countries aviation authorities to establish exact particulars of the route.
It is his belief that “MH370 likely flew in the shadow of SIA68 through India and Afghanistan airspace. As MH370 was flying “dark” without transponder / ADS-B output, SIA68 would have had no knowledge that MH370 was anywhere around and as it entered Indian airspace, it would have shown up as one single blip on the radar with only the transponder information of SIA68 lighting up ATC and military radar screens.”
He is also adamant that SIA68 could not have detected MH370 as the Boeing 777 utilizes a TCAS system for traffic avoidance; the system would ordinarily provide alerts and visualization to pilots if another airplane was too close. However that system only operates by receiving the transponder information from other planes and displaying it for the pilot. The MH370 was flying without the transponder, so it was invisible to SIA68.
So where did it go? Keith Ledgerwood believes that the TCAS system onboard MH370 would have enabled the pilot(s) to easily locate and approach SIA68 over the Straits of Malacca and would have shown them the flight’s direction of travel and the altitude it was traveling which would have enabled them to perfectly time an intercept right behind the other Boeing 777.
So according to Keith Ledgerwood, once MH370 was safe from being detected by military radar sites in India, Pakistan, and Afghanistan it would have been free to break off from the shadow of SIA68 and could have then flown a path to any of several locations along the flight path of SIA68 where it could have easily broken contact and flown and landed in Xingjian province, Kyrgyzstan, or Turkmenistan. Each of these final locations would match up almost perfectly with the 7.5 hours of total flight time and trailing SIA68.
So according to Mr Ledgerwood his theory answers a host of oddities that don’t make sense otherwise, like the seemingly haphazard route and the sudden northwest heading towards the Andaman Islands, noting that the timing and evasive actions seem deliberate, after someone went through great lengths to attempt to become stealthy and disable ACARS, transponder/ADS-B (even though SATCOM to Inmarsat was left powered).
In conclusion the author believes that MH370 snuck out of the Bay of Bengal “using SIA68 as the perfect cover, entered radar coverage already in the radar shadow of the other 777, stayed there throughout coverage, and then exited SIA68’s shadow and then most likely landed in one of several land locations north of India and Afghanistan.”
