Eurocopter AS-350 AStar (PR-TNG)

The AStar is a popular helicopter, over 10,000 have been produced since 1975. They can carry five people and fly about 150 MPH. New they cost pert near two million, used ones can be picked up for about half that. All in, they cost about a thousand dollars an hour to operate. You must really want to get somewhere to pay that kind of money.

The airport code attached to this picture is SSPF. Mouse over the code and we get a popup that says Fly Village (Altos/PL). There is a Fly Village in northeast Brazil. However, SSPF is the code for an airport closer to Sao Paulo, way farther south.

Teresina, Fly Village & Natal, Brazil

Fly village is not far from Teresina, and we got another photo of a military plane in Teresina. Alexandro Dias took both photos, so we're probably in Teresina. Natal used to be the jumping off point for planes flying across the Atlantic to Africa.

Rock art at Serra da Capivara National Park in Piauí state, one of the largest and oldest concentrations of prehistoric sites in the Americas

Fly Village is located in the Brazil state Piaui. Looking at Piaui I find this cool photo of ancient rock art. The rock art might be 20,000 years old. They figured that out using optically stimulated luminescence. Wait, what? Optically stimulated luminescence? Never heard of it.

I looked. Optically Stimulated Luminescence is some real Star Trek shit. It sounds like complete bullshit, but evidently it works. Not only are they using to date cave paintings they use it with dosimeters. It sounds insane.
