Helicopter Operations.

Helicopters were our sole means of transport. We experienced problems and delays with every move except the first, either through poor weather conditions or mechanical problems. The crews must have heaved sighs of relief when our event finished. We were underweight but our cargo was bulky, which caused some cramped moves. A further problem was that in most cases we were near maximum helicopter range, which left little scope for reconnaissance. Our basic cargo is shown in Table 1. Modifications between moves arose through resupplies of food, antifreeze and fuel and samples, which were retroed after each move.
