Questions remain unanswered as EgyptAir flight MS804 from Paris to Cairo crash into the Mediterranean Sea on May 19. According to updates, forensic experts managed to recover body parts of some of the passengers. In a recent one, Egyptian authorities confirmed that wreckage from the plane was identified from the Mediterranean; however, the black box remains to be missing.

The EgyptAir flight 804 vanished on May 19 with 66 passengers on board. A few weeks ago, French and Egyptian authorities detected a "ping" from the plane's black box using the state-of-the-art technology of a French search vessel.

And in a recent statement, Egyptian investigators announced that they have found wreckage from the missing EgyptAir plane. Authorities said that "several main locations of the wreckage" had been identified, according to a report by BBC.  One of the search vessels already sent back images of the wreckage, the report added.

The recovery of the identified debris is now being studied with the help of the John Lethbridge Search Vessel. Experts are mapping the locations of the identified wreckage of EgyptAir's Airbus 320 plane to aid in further investigations crucial in finding out whether the plane crashed intact or not.

With the identified parts, the investigators will use a mapping technique to help identify the possible distribution of all the debris before proceeding to the retrieval process.  The mapping might be able to help locate every single part of the plane, including where the black box is located.

Through the mapping results, investigators can analyze if the plane exploded mid-air or if it crashed intact and broke upon contact with water. Investigators who have worked with similar cases before are confident that they will be able to tell from the wreckage if the plane was downed by an explosion or not.  However, retrieval and further investigations would not be easy and are expected to last for months.

Experts' fear is that the time for a black box to emit "ping" or signal is about to lapse, but according to the report by BBC, the John Lethbridge vessel is capable of detecting the black box even without the signal.

But despite that, the black box has to be found to shed light to the mysterious downing of EgyptAir Flight 804. Once located, the debris and the black box will be sent to Egypt, according to a civil aviation official in an interview with CNN.

The U.S. is said to send its own team to help Cairo in the recovery and investigation of Flight 804 debris, which will include a recorder specialist with a high level of expertise in analyzing black box data.
