You would obviously never want to be beset by a heart attack, but perhaps the last place in the world you'd want it to happen is when you're taxiing an airplane to the runway.
This is exactly what happened to a captain of a KLM aircraft, who became unwell as he was about to leave Glasgow Airport for Amsterdam.
Luckily, he was resuscitated by the crew with the help of an on-board passenger.
Firefighters from Glasgow Airport helped take the Dutch pilot off the plane. He was met by ambulance crews and taken to the Golden Jubilee Hospital in Clydebank.
The co-pilot of the plane, which had 128 people on board, took the aircraft back to the gate.
The flight was supposed to leave at around 5pm, but because of the emergency it was cancelled. Passengers on board had their flights re-booked.
A spokeswoman for KLM said: "During taxiing to the runway on this KLM flight to Amsterdam the captain became unwell and the staff treated him with the help of a passenger.
"He was taken to hospital where his condition is stable."
A spokesman for the Scottish Ambulance Service said: "We took a call that a man was having a heart attack at Glasgow Airport. We attended the scene and arrived at 5.25pm."
