Protesters who caused hundreds of flights to be delayed following a demonstration at Stansted Airport in Essex have appeared in court.
The group of 22 objectors appeared at Harlow Magistrates' Court charged with aggravated trespass.
Each protestor was fined up to £120 and given a community service order.
Leo Murray from Plane Stupid, which organised the event, said: "We always expected to end up in court." BAA said unlawful behaviour was unacceptable.
Mr Murray said: "That's the point of peaceful direct action. You do something that you believe is necessary and hold your hands up to consequences."
The protest on 8 December aimed to highlight the impact of aviation on the environment.
BAA said irresponsible or unlawful behaviour which aimed to disrupt the airport was unacceptable.
