Was it an explosive inside the aircraft that caused it to crash in Ghatkopar on June 28? On Wednesday, the Ghatkopar police asked the state FSL if there was any explosive residue found in the debris.

K Y Kulkarni, acting director, State FSL, Kalina, said, "We have been asked to find out the reason for the explosion. Also, the sealed samples that were collected from the crash site were submitted to us, and we have already started the probe." When asked to elaborate, Kulkarni said, "Our General Analytical Department (GAD) scientists will ascertain the nature of fuel found in the debris. We will also look for presence of any other explosive material. The police are keen to know if there was any inflammable material, other than aviation fuel, or explosive material inside the plane that could have triggered the fire and crash. We will complete our study and submit our report."
