My thoughts of late have been drawn towards the Haitian earthquake relief and how simple technical solutions could mitigate similar crisis in future disaster situations. I believe that it should be possible to develop a cheap and effective aid delivery system that could safely distribute essential supplies to any point on the globe within a few days of any disaster. The aim would be to prevent many of the permanent injuries and deaths caused by infections and dehydration which are rarely addressed in time by current aid efforts. The early and widespread provision of aid may also minimise the chance of widespread looting, making it safer for subsequent aid teams to operate.
To respond quickly, the initial aid would probably have to be airlifted in. However, the local airports and associated transport infrastructure may not be able to cope as we have seen in the recent case in Haiti, and helicopters don't have sufficient range for delivering to most destinations. One method of circumventing this problem would be to parachute pre-prepared supplies from fixed wing aircraft. Unfortunately, it isn't usually advisable to drop supplies onto non-secured areas due to the danger of injuring people on the ground, and even if they were dropped safely there would be a danger of them being monopolised by the less needy. Whilst it may be possible to use paratroops to secure the landing zones prior to the main supplies being dropped so they can be distributed fairly, these troops would have limited support if anything went wrong. They would need to protect themselves and control crowds, which is not always a practical proposition in the more unstable regions of the world.
I propose a system in which the initial aid relief can be dropped in multiple small lots distributed over a wide area. The reduced mass of each parcel means they can be dropped over unsecured areas relatively safely without injuring people on the ground, although a prior warning by dropping leaflets would further minimise the chance of injury. The drop zones could also be restricted to park areas and the less populated spaces surrounding the towns and cities.
An ideal arrangement would be one where the supplies can be dropped quickly from the aircraft hold, avoid the entanglement of parachutes and safely impact on the ground without hurting civilians. Whilst it may be possible to envisage a system where multiple small lots are parachuted individually, to simplify the design it is suggested that each aid box should weigh about 25-50kg and be attached to a single parachute. However, this box would contain several hundred smaller lots of aid such as bottles of water, food, or medicines weighing about 250 grams each attached to one another using a foam-covered belt folded into the box.
When the aircraft is immediately above the drop zone, each box and attached parachute is pushed out of the rear of the transport aircraft as is usual with airdrops. However, as the parachute opens the tension in the cable would rip open the box and drag out the belt spreading the mass of aid out over several tens of metres rather than being concentrated in one lethal mass. One emptied, the cardboard box would be attached to the opposite end of the belt, which would land first providing extra warning and cushioning on impact. However, most of the belt would probably land along a stretch of ground so civilians can easily access it without excessive crowding. A typical C-130 aircraft would be able to transport and drop about 400 to 800 boxes or 80,000 lots of aid in one trip.
The medical aid package would also include simple instructions to civilians on how to administer fluids and treatment to the injured. Therefore, the emphasis would be on providing civilians with the means to help victims by reducing infection rates and maintaining a level of life support until more professional help arrives. Air dropping supplies in this fashion would also reduce pressure on overtaxed existing transport systems which could be spared for moving heavier equipment and emergency teams to the disaster area.
