My husband sat in the front seat next to the pilot and I sat in back. No doors means it's windy. If you do doors off and have longish hair, I suggest a headband or bandana to keep your hair from whipping about your face/eyes.
The pilot has the best office in the world! He was very knowledgeable about the island and its history, the flora and fauna too. It was an amazing experience and we got some beautiful photos.
