There's no need to worry if you notice the emergency services at the airport today.
Ronaldsway Airport took to Facebook to explain it's just an exercise.
It says it's conducting a tabletop simulation of an emergency to test the response from the Island's blue-light services.
In its post it says there's no cause for concern and it won't affect flights or operations.
