I thought it was at Bahrain not AKT. The pallets had been transhipped from a TriStar to the Hercules. The T* had been converted to Kgs but the Hercs were still in lbs. The pallet weights were taken as being in kgs and converted to lbs but they had already been converted. So the load was double what it was manifested as. The Herc got off the ground....just, made a circuit and landed.
We all said it was an accident waiting to happen introducing the change over from lbs to kgs gradually, aircraft type by type rather than in a one hit.
