A number of people have been rated by paramedics at Shannon Airport after their flight has made an emergency landing this afternoon.
British Airways BA-2201 flew from Gatwick Airport to England to Cancun in Mexico when the crew made a reverse turn over the Atlantic Ocean and departed to the midwestern airport.
Aboard the Boeing 777-200 had 237 passengers and a crew of 13 people.
The crew reported that it had found fumes in the cockpit and the passenger cabin, and that the number of persons on board seemed to have been affected and would have to be checked by paramedics upon arrival.
On the ground at Shannon, the authorities undertook urgent procedures before the flight arrived. This includes alerting the HSE, the National Emergency Service and An Garda Síochána.
Five ambulances, two modern fast-track vehicles and an ambulance were sent to the airport.
Several cabin crew members were rated by paramedics, but it is not known whether passengers are affected.
The flight landed safely at 3.18 am and was hunted down the runway by the airport fire and rescue teams, which also accompany the jet to the terminal.
After being confirmed that their flight had been canceled, passengers were transported by bus to hotels in Clare and Limerick. It is expected that a replacement airplane will be shipped to Shannon tomorrow to take passengers to their destination.
A British Airways spokesman confirmed, "We are very sorry for the delay of our customers' trips. We gave them premises after their departure to Shannon due to an insignificant technical problem.
"The safety of our customers and crew is always a top priority and we will never run a flight unless it is safe to do so."
