The Foreign Office is advising against travel to the northern Sinai region of the country after the Russian jet came down and UK flights have been suspended.
Thousands of stranded Brits still in Sharm El Sheikh began flying home on specially charted flights ordered by the British Government today.
A government spokesman said: " We investigated the reported incident at the time and concluded that it was not a targeted attack and was likely to be connected to routine exercises being conducted by the Egyptian military in the area at the time."
In a statement, Thomson Airways confirmed that an event was reported by the crew of flight TOM 476 on 23 August 2015.
It added: "Upon landing into Sharm el-Sheikh, an initial assessment was conducted and the event was immediately reported to the UK Department for Transport (DfT) in line with established protocol."
"The DfT conducted a full investigation in conjunction with other UK Government experts. After reviewing the details of the case, the investigation concluded that there was no cause for concern and it was safe to continue our flying programme to Sharm el Sheikh."
