C-130J Crash: Why the mystery?

  C-130 J Crash: What are the real reasons?
      The crash of  Lockheed Martin Super Hercule  transport plane operated by Indian Air force on 28th March  2014 is increasingly getting mired into controversy.  A  front page news report on the Indian Express of 23rd April 23, 2014 further corroborates the evidence of a clumsy attempt at cover up.  One needn't suggest that the report is deliberately planted to test the public opinion on behalf of vested interests. Though major Indian newspapers and influential media houses  are known to act a PR houses of leading arms sellers in the world. The very  reporting containing self-contradictory assertions point  to a deeply disturbing state of affairs  in India’s national security arena in which mainstream  press and government collaborate to fudge the facts  and prevent outflow of truth at the cost of grave harm to national interest.
     The report’s seemingly feeble attempt to attribute the crash to ‘Wake turbulence’  is laughably silly and flies in the face of basic scientific and technical facts.  Though it , in same breath qualifies the  so-called findings  with the statement that a final report is still underway.  So the purpose seems clear. Blame it on the crew  and exonerate the manufacturer who hasn’t even made the voice  recorder data  public till date  as the manufacturer is investigating himself!
    The  technical and scientific facts  would point against ‘wake turbulence’ as a cause of crash.  Wake turbulence is caused by  an aircraft in flight leaving behind extremely volatile vortices  making it dangerous for any tailing  aircraft not maintaining a safe distance.  Of the two  major components of the turbulence,   wingtip vortices and  jet wash created by high-speed gases expelled by jet engines, the former are the real danger due to their longer persistence in air.  These are known to be of concern during take-off and landing but rarely in mid-flight. Besides , military aircrafts are designed to fly in formation controlled by a common command  centre normally resident in the leading plane.  The flight control is transferred to the leaders on board computer making distance separation between planes automatic.  Hercule   is designed to sustain  turbulences of incomparably higher intensity than those created by her powerful engines and flight behavior.  Any good graduate student of mechanical engineering will  discount the possibility of  such a heavy mass  falling prey to rapid air circulation possible on a calm and clear sky over Agra.  The repositories of crashes histories  of the plane make it the first case if turbulence is the cause.  In case the tailing pilot of the C-130J ploughed into wing tip vortex of the leading plane,  the error  lies  surely at the doorstep of the commanding computer module not at that of the crew.  Independent access to flight data recorder and other onboard control data would give real reasons but they are unlikely to be made accessible before an impartial investigation effort. The reason:  the bear bug of national security again that may open up many inconvenient question for the government and manufacturer. Hence the report by Indian express is a helpful   push to the cause of national security.
Possible causes:
"The accident happened just before the identified 'drop zone' when the aircraft, flying at a low level to evade enemy radars, slows down quite a bit to offload paratroopers or equipment. There was no radio exchange between the ill-fated aircraft and the other C-130J in the front... there was no warning,"  According to a report published in another leading national newspaper TOI on 5 April 23, 2014.  
   This would rule out waking turbulence theory.  The another  conspiracy theory floating around pointing to  Chinese faulty parts  would obviously  be a motivated report to deflect attention  as faulty parts, if any, would be exposed in any investigation. Besides Hercules are not manufactured like hamburgers in Mcdonald.  They carry the manufacturing and technological prowess of worlds’ leading super power.  If that too doesn’t stick, we can bring in Pakistan soon enough.
      Accident happened  so fast  at a low altitude that it gave no time to crew to eject from a crashing plane.  A terrestrial projectile attack  would had also given the crew enough time to eject to safety. Was there any such  unidentified assault on the plane  from ground?   Or massive radio interference for a very short duration  from a nearly located source?  The preponderance of  radio-wave emitting  sources  i.e  towers,  low voltage power cables, amateur radios and cell phones etc   makes a low flying plane’s controls vulnerable to jamming.  In any case the final report is awaited.  People of India may know.  Or may not owing to reasons of ‘National Security’ !   At least we  can trust mainstream national press to be on side of those who believe people of India are not the best guardians of their national security.
