A close view of the two Boeing CH-47 Chinook of the United States Army that arrived at Tobias Bolaños airport in Pavas Wednesday morning.

They look pretty new.

To give an idea of the size of these helicopters, they measure 30 meters long and weigh more than 20 tons.

The CH-47 Chinook is an American twin-engined, tandem rotor, heavy-lift helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol (later known as Boeing Rotorcraft Systems).

The CH-47 is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of modern-day Washington state.

The first flight was on September 21, 1961. Currently still in production, over 1,200 have been built as of 2012. Unit cost is US$38.5 million dollars. (Wikipedia)
