September 22nd:

14:55 (Sydney time, 04:55 GMT) Oceanic 815 departs from Sydney.

11:00 GMT - the flight loses radio contact six hours after takeoff and turns south to circle back towards Fiji

Desmond follows Kelvin to the cove, finds his boat and gets into a fight with Kelvin. Desmond, presuming Kelvin is dead from the headwound he received, takes the Fail-Safe key and rushes back to the Swan, but the counter has already reached zero, causing a system failure. He eventually enters the numbers and resets the timer, discharging an EMP.

13:00 GMT - Eight hours after takeoff, Flight 815 encounters turbulence from the Swan's System Failure, and breaks up in the air over the island. The EMP sends a shock wave through the Others' camp, interrupting the book club discussion at Juliet's house. The Others gather outside and witness the breakup of the plane.

This is roughly 03:00 local time on the morning of September 22, since the plane has crossed the international date line. This timeline does not correspond well with the daylight at the time of the crash or the time stamp in the log printout. Note: It is also possible that the plane may have been flying West rather than East. In this case, the island would be located near East Africa, placing the crash at 4:16 PM local time and explaining the drug smugglers plane and the timestamp in the log printout.ut.
