Tropical Survival - Immediate Considerations
There is less likelihood of your rescue from beneath a dense jungle canopy than in other survival situations. You will probably have to travel to reach safety.
If you are the victim of an aircraft crash, the most important items to take
with you from the crash site are a machete, a compass, a first aid kit, and a parachute or other material for use as mosquito netting and shelter.
Take shelter from tropical rain, sun, and insects. Malaria-carrying mosquitoes
and other insects are immediate dangers, so protect yourself against bites.
Do not leave the crash area without carefully blazing or marking your
route. Use your compass. Know what direction you are taking.
In the tropics, even the smallest scratch can quickly become dangerously
infected. Promptly treat any wound, no matter how minor.
