Last friday, I was driving in Ave El Dorado, passing all the hangars before reaching Puente Aereo, and in the hangar were the old 707 FAC001 used to be for a for a long time, I saw a beautiful wingleted 727 (Sorry, couldn't take any pic). It was white and had a big COSMOS on the fuselage. It was parked just outside the hangar facing the street, like if he wanted to jump over the fence. Anyway, 727s are one of my all time favourites ac, and since I haven't seen many wingleted ones, anyone has any info on this one? Is it a cargo ac, HK- registered and what's COSMOS (never heard of it)??
Thanks for your answers.
