Since it became almost obvious that missing Malaysia Airlines (MAS) MH370 was delibrately flown from South China Sea to Andaman and then flew almost 6 plus hours to either Central Asia or Southern Indian Ocean, people are trying to figure-out how a wide-body aircraft like Boeing 777 can fly without being detected. Since this is highly unlikely, many experts believe that the MAS Boeing 777 probably flew to South than North. Since none of the 25 countries looking at their radar records could locate an unidentified plane, it would have flown to the south. Or maybe very low?
An interesting theory which is going viral involves another Boeing 777 belonging to Singapore Airlines. Singapore Airlines Flight 68, SIA68 namely.
Keith Ledgerwood, has plotted the route taken by the missing MAS plane and then looked for another plane which was there around that time and found out that SIA68 was passing through there and flying to Europe to its final destination of Barcelona, Spain. Indeed, the unusual Singapore Airlines service flies from Singapore to Barcelona and from there to Sao Paolo.
Basically, Keith Ledgerwood calculated that MAS plane was at 1815UTC when military radar lost contact. At the exact time, SQ68 was also there:
Keith Ledgerwood theorizes that if MH370 indeed followed SQ68, it would have been free to break off from the shadow of SIA68 somewhere in Cental Asia and then land in Xingjian province of China, Kyrgyzstan, or Turkmenistan.

It is my 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.Although another commercial plane would not see MH370 on TCAS system, MH370 could easily see all commercial airlines nearby! MH370 would see the direction, speed and altitude of other airliners (see below)!
Wouldn’t the SIA68 flight have detected MH370? NO! The Boeing 777 utilizes a TCAS (Traffic collision avoidance system) 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. If MH370 was flying without the transponder, it would have been invisible to SIA68.
