Long ago there were helicopter service for the travelers to Machu Picchu. Helicopter reached the people up to Machu Picchu ruin. But the service was discontinued as the vibration was harmful for this century old ruins. Recently Inkaterra got permission to fly again. They started in June, 2006 and brought lot of travelers from Cusco to Machu Picchu. But due to the protests of environmentalist this service was suspended last year.
This year Helicopteros del Cusco S.A. (Heli-Cusco) made some environmental impact study on Machu Picchu. They tried to proof that if heliport is located outside the citadel, then there is actually no harmful effect of helicopter on Machu Picchu. Finally The INRENA (National Institute of Natural Resources) approved the resumption of commercial operations in helicopter to Machupicchu and ruled out that any type of environmental impact in the zone of the sanctuary exists, whether sonorous or by vibration. This resolution allows Heli-Cusco to operate in Machu Picchu. So the same heliport, which was used by Inkaterra, is being used by current operation.
National Institute of Culture (INC) of Peru opposes the decision of starting the helicopter operation. INC director Jorge Zegarra Balcázar said that this permission should not be offered to the company Heli-Cusco because the sanctuary is being damage in different ways. He also complained that Heli- Cusco gives false information stating the helipad is three kilometer away from Machu Picchu citadel, which is actually only one kilometer away aerially from Machu Picchu.
There was a series of meeting of the Machupicchu Unit of Management (UGM) to discuss the helicopter operation in Machu Picchu. The regional government, the INC Cusco, the INRENA and the Department of Tourism participated in those meetings. One of the factors that favors the use of helicopter flights is the APEC summit and the consequent protection of the heads of state.
