The action took place on flight TP1921, which should have left Francisco Sá Carneiro airport for Lisbon at 9am yesterday, which only happened at 9:34 am, a source from Climáximo told Lusa, who denounced the route with 18 daily flights.

According to the same note, the activist, “upon boarding the plane, refused to sit down and take off, in protest against what he considers a “climate bomb” that “emits tons of carbon dioxide into the air of our country, on a route with road and rail alternatives with comparable times and costs, and compromises people's present and future”.

“Upon exiting the plane, the Climáximo supporter encouraged everyone to stop consenting to attacks on our lives, such as short-haul flights,” he said.

Lusa contacted TAP, which referred the matter to the PSP as it understood “it was a police matter”.

A source from the PSP's Porto Metropolitan Command confirmed the incident, stating that it was a man who “delayed the flight by 26 minutes” and who “was removed by agents” from inside the aircraft, after which he was identified and released.

Quoted in the press release, Francisco Siqueira, spokesperson for the action, asks: “if a flight would not take off from the ground due to a bomb threat, why does it make sense to take off when its very existence threatens the lives of so many people?”, and goes on to remind us that “aviation is the fastest and most unfair way to burn the planet, but there are no signs of it slowing down”.

In the same note, when answering the question he raised about “who does so much aviation serve?”, the spokesperson stated that it was “certainly not the vast majority of people who suffer from the lack of free, quality public transport for the most basic needs, such as getting to work”.

Climáximo considered the 18 daily flights on the Porto-Lisbon route “an act of violence that needs to stop immediately – it could stop today”, it said in the statement.

Francisco Siqueira added that “TAP and the airlines that operate these flights must be held accountable for releasing these carbon bombs,” and demanded “a free, electrified and efficient public transport system for all people, and not more planes crossing the sky.”

A week before the polls, the committee highlighted that “stopping the climate crisis is not yet in the electoral section, visible in the consent by all parties to the decision to build a new airport in the midst of the climate crisis”.

He therefore argued that it is “necessary to build popular power to stop the climate crisis, for the right to the city, a habitable country for all people, free public transport for the people, the reduction of aviation to near zero by 2030, and not one more project that increases emissions - such as the expansion and creation of new airports”.

The Climáximo statement ends with the announcement of the “Stop the planes” protest at Lisbon airport on June 1st, with the meeting point at 3 pm at Alameda D. Afonso Henriques.
