years and an acclimatisation session was held for drivers to learn the circuit. As he did not have the necessary super licence to take part in the Grand Prix, Londoño was allowed to drive in the session and did ten laps of the track with his best lap four seconds slower than session leader Carlos Reutemann. However, Keke Rosberg was irritated at Londoño and braked earlier than expected in front of Londoño and this caused the latter to hit Rosberg. Londoño was not granted his super licence by the Fédération Internationale du Sport Automobile as his team had not provided the necessary information and he was judged to have caused the crash with Rosberg. The refusal of him being granted a super licence was also attributed to Formula One's commercial rights owner Bernie Ecclestone discovering Londoño's links with the Medellín Cartel and Escobar. His team kept the money he brought to them but elected to draft Marc Surer who finished the car in fourth place. Nevertheless, despite the controversy, Londoño was the first Colombian driver to have taken part in a Formula One race weekend. Final motor racing years Due to his national support, Londoño participated in three Formula Two races for Docking-Spitzey Team-Toleman after managing to convince the team's manager Alan Docking via telephone to recruit him for 1981. Although he qualified last for the Pau Grand Prix he took advantage of a slippery track and other cars retiring due to mechanical problems to finish ninth. Londoño's next race was at the Autodromo di Pergusa and retired after twenty-five laps with an engine failure in spite of a good qualifying performance. A mechanical issue sidelined his race at the Circuit de Spa-Francorchamps after fifteen laps, and was unable to start the Donington Park round after crashing in the warm-up session. At the end of 1981, Londoño returned to Colombia, and won the Grand Touring class of the 3 Hours of Medellín. Several of his sponsors were arrested by police before he could partake in a planned 1982 venture into Can-Am and thus did not race in that year. In 1983, Londoño partook in three races of that year's IMSA GT Championship and did not have a large amount of success apart from a sixth-place finish alongside co-driver John Gunn in a Phoenix JG1 at the Daytona 250 Miles. The following year, he remained as a competitor in the IMSA
