Stray balloon in fog causes flight delays at Gatwick "We are aware and are trying to assist in locating the balloon," a force spokesman said. We've not been able to do anything about it becuase it's really foggy. We've had officers looking into the sky and they can't see anything. In a separate incident this morning a hot air balloon crashed into power lines near West Haddlesey, North Yorkshire. All the passengers are safe. The cost of the delays to Gatwick are unknown but the airport could face fines from carriers, a spokesman said. It would depend on the reason and length of the delay. This is very unusual so it is something that will be looked into," he said. The balloon pilot could be prosecuted by the Civil Aviation Authority and handed a fine if they are found to have breached air navigation regulations.
