well I can accurately say that it was a bomb on board and hopefully shed some light on afew of the rumor's. SCAMA announced that it was due to fatigue, absolute rubbish, but no shock in a country where corruption rules and control of the airspace is being tightly fought over.
The background to this is rather interesting. This route is normally flown by Turkish airlines. yesterday they didn't come into HCMM, this in itself is a strange occurrence as they are in everyday, it was cited as a technical problem. Today was the same, no Turkish airlines. Daallo was flying this route for Turkish today, pax were briefed that Turkish would meet them in Djibouti. Today on check in the Turkish desk was closed completely and all manifests and tickets were hand written, and as usual it was complete chaos.
Word on the street( from very good sources) is that Turkish knew that there was going to be an attempt to down an aircraft and in particular Turkish airlines, this could be possibly linked to money that is collected by AS, there has been a lot of insurgent activity of late and a no of assassination attempts on airport workers who work for Favori. Turkish airlines and Favori are also in bed with SCAMA, they are exempt nearly all fees and may of received a tip off( so the word goes).
The explosion happened not long after take off, it took off from runway 05 end going out over the city and climbed out over the sea, it remained out over the sea to gain altitude before setting a heading for DJB. The aircraft had reached approx. 14,000 AGL, the seat lights had just been switched off when the explosion happened, oxygen masks deployed, but none of them worked. the pilot took an immediate turn to the left and descended at a steady rate. The pax reported slight heavy breathing and tightness of the chest, possible early signs of hypoxia or due to the explosion, there was a strong burning smell and one pax near the scene reported that the smell was not too dissimilar to a bleach like smell ( quite common with certain explosives )
The report of the pax falling out is yet to be confirmed but it is believed to be true and that it was the guy who triggered the explosion. the other casualty was sat just across and had all his clothes blown off him but is alive.
