Several thousand protesters protested against the growth of aviation in six cities. With banners with inscriptions like "Aviation grow the earth glows", "Aviation worries", "Save peace in Hoenderloo" and "Emergency landing for the climate", they oppose the increase in the number of flight movements.

The protests were often encountered in red clothes at the beginning of the afternoon in the city centers of Amsterdam, Eelde, Eindhoven, Maastricht, Rotterdam and Zwolle. With the clothes and attributes they would "give a red signal" to the government that the limits for air traffic have been reached.
