WFP South Sudan for the first time used the so-called sky pack system to airdrop High Energy Biscuits (HEB), ready-to use supplementary food (RUSF) as well as water, blankets and medical kits. The sky pack system is a box without parachute that contains small envelopes with the items. It opens when dropped, letting the same slowly floating to the ground. This will allow WFP to reach beneficiaries on the move without having presence on the ground. The test drops of 768kg of HEBs and RUSF plus the other items in Ganyal, Unity State were 100 per cent successful.
