Philippine C-130 Plane crash–a terrorist attack?

Though they have’nt confirmed it yet, speculations abound that the MILF is behind the shooting of the Hercules C-130 plane. After initially accusing the MILF of complicity, the AFP now says they are discounting the possibility of a terrorist attack. However, a thorough probe would reveal that before the C-130 crashed into the waters of Davao Gulf, smoke bellowed from its body, signifying that it was hit by something. Many say, the lightning that the locals saw was a missile hitting the body of the C-130 plane. 

This early, the AFP particularly the Air Force is enforcing a news blackout on this incident, to avoid further speculation. However, sources from the retrieval team says there’s a huge hole in the plane, bolstering suspicions of a terrorist attack. Its known within the intelligence community that there are groups of MILF rebels based in Davao City. There are also some units of the Jemaah Islamiyah and the rogue Abu Sayyaf Group in Davao. There is a strong possibility that this crash could be the handiwork of these groups out to sabotage the peace process in Mindanao.

If this is true, then, we have a very serious situation at hand because apparently, these rebels have modern, sophisticated arms including possibly a surface-to-air missile.
