There's a picture of this aircraft in the latest Airliners magazine - registration is N535AW (a US rather than a Colombian registration). Further, according to the magazine, the plane is a 767-33A, line number 25535, construction number 491. I rather like the tail logo, which resembles a blue, orange, and red butterfly... very nice!
The aeroplane has unveiled for us the true face of the earth. -Antoine de Saint-Exupery
