BA 747 cargo fire
A British Airways B744 returned to Sydney this afternoon with a cargo fire warning. According to passengers the cabin was "hotter than usual" and cabin staff were moving briskly around the cabin apparently trying to find the source.
The aircraft landed safely and all passengers made egress through the L1 via stairs althought the aircraft was still on the runway.
Looks like the real thing. Personally, this is my worst nightmare.
