Fabián Penín, a 58-year-old private pilot who posed as a control tower operator at Buenos Aires’ Jorge Newbery Airport, was arrested after clearing an Aerolíneas Argentinas flight bound for Bariloche for take-off. The Aerolíneas captain, Martín Mucciarelli, noticed some incoherence with the vectors indicated by Penin and did not proceed with the take-off.
