MAF is Missionary Aviation Fellowship.
A Twin Otter is a type of airplane.
Papua New Guinea, as you will see in today's click through, is a rough and rugged area which is not a place in which you would want to casually fly an airplane.
The location of the landing we will see today is Maramuni in Papua New Guinea.
The length of the landing strip is 450 meters by 15 meters.
The altitude is 4800 feet.
As you can see -- if you can't use an airplane, getting in and out of this area for emergencies, sickness, supplies, etc. is almost impossible.
That is why MAF provides such an awesome service to remote areas such as this and to remote areas elsewhere in the world. WOW. This is not for the faint of heart.
