In response to the Election debate from the 15th of February, Lucht- en Ruimtevaart Nederland (LRN) has issued a press release.
Because of new (Dutch) innovations low-noise aircrafts can be built, which makes the expansion of airport Lelystad less urgent. The government should stimulate the production of quieter aircraft and -engines, so that local residents of Schiphol experience less disturbance and Schiphol will be able to expand. This will be beneficial for the residents as well as the Dutch economy.
