A touch surprised that this has not already been posted.
From Aviation Analysis:-
A Russian Sukhoi Su-30SM fighter jet has crashed in to the Mediterranean sea, off the coast of Jableh city in Latakia, Syria, on Thursday morning.
The two pilots onboard the twin seat fighter died in the accident.
The aircraft crashed shortly after taking off from the Russian Khmeimim Air Base, also Hmeimim Air Base, located south-east of the city of Latakia in Hmeimim, Syria.
Russian Defense Ministry cited possible bird strike for the accident citing preliminary investigation.
Bird strike but no ejections?
RIP for the two crew & condolences to families.
