Protesters Cause Delays At World’s Largest Airport
Climate change protesters in London caused a few delays at one of the world's biggest airports.
The group, going by the name “Plane Stupid", chained themselves to gates and displayed banners on the tarmac at Heathrow Airport.
They're against plans to build a third possible runway at the airport.
The two runways are still open.
But Monday's demonstrations caused some planes to be delayed and others canceled.
The airport says it expects more delays throughout the day.
