From the Wikipedia article

Operation Gardel was the codename given by the Peronist guerrilla organization Montoneros to the downing of a Lockheed C-130 Hercules, belonging to the 1st Air Brigade's 1st Transport Group as it took off from the old Teniente Benjamín Matienzo International Airport, carrying 114 Gendarmerie personnel as part of a military intervention in Tucumán province.

Background

The plan was to set off an explosive charge in the form of a conical tip placed below the runway when the C-130 was to be at full throttle during takeoff.

Near the middle of the runway some 1,100 meters away from the northern end and 1,000 from the southern, a disused sewer led to a storm drain. A cable was laid through the 250-meter tunnel, emerging from the storm drain and connecting the charge to the 12V battery of a parked vehicle. The switch would be activated from a nearby pit.

This "masterpiece of military engineering", referred to as such by Montoneros, had taken at least six months of planning; the fork of a branch was used as a benchmark to calculate the plane's trajectory.
