More details have emerged of the Trans Arabian Air Transport Boeing 707-320C accident in Lake Victoria, Tanzania, on 3 February. The aircraft came down during a night landing 4km (2nm) from the threshold of Mwanza's runway 12 during its second approach.

After a go-around, the captain began a left-hand circuit, but crossed the extended centreline and decided to carry out a right-hand loop on to the final approach.

According to the Tanzania Accident Investigation Branch (AIB), the aircraft was observed to become "unstable" during the turn. Air traffic control warned the pilots that they were very low before the aircraft hit the water.

The AIB says the captain's altimeter was reading 4,100ft (1,250m) and the co-pilot's 3,720ft, the latter being the correct elevation of Lake Victoria.
