ChatGPT summary:
Swiss Airlines miscalculated the weight of its new First Class seats, leading to balance issues on their A330 planes. To correct this, they plan to install lead plates as counterweights, adding around 1.5 tons to the aircraft. This solution has raised concerns about fuel efficiency and environmental impact. Despite the weight issue, Swiss assures that their current flight routes won't be affected.

*facepalm*
