Re. the 'steak runs', we used to do similar with the Valettas, mid 50s.Two incidents - Phil H couldn't get his tail up on first take-off attempt, so aborted and checked loading. 400 lbs plus assorted meats stowed in the chain locker!!! More balanced arrangement for second (successful) attempt.
Later trip with similar, large, consignment had engine problems en-route and had to divert into Hargeisha. 3 day stopover, no cold storage, VERY 'pongy' cargo off-loaded and many out-of-pocket results.
