KOTA KINABALU, April 30 — The family of the late Tun Fuad Stephens has questioned the veracity of latest declassified report on the Double Six tragedy, casting doubt on findings prepared by the manufacturer of the crashed plane.

The three surviving children of the then-Sabah chief minister, who was among 11 people killed in the 1976 crash of the Sabah Air Nomad GAF N-22B, said they suspected the integrity of the report as the manufacturer could have a motive to minimise responsibility.
