"The UK Government appears to be quite concerned over security matters in and around Sharm El-Sheikh today. This adds some credence to the hypothesis that an explosive device may be responsible for the event," Martin Alde stressed.
According to Alde, it is highly likely the plane did not break into pieces at once while in midair.
"The continued availability of the data signals suggests that the aircraft did not immediately completely disintegrate. If that had occurred then usually such signals would cease. This hypothesis aligns with the fact that the tail and rear fuselage were found quite separate from the main wreckage," Alde noted.
What has become the largest civil aviation disaster in Russian and Soviet history claimed the lives of all 224 people on board the aircraft operated by the Russian carrier Kogalymavia.
