Fainting, heart attacks, and death. How pilots handle medical emergencies in midair.

• An easyJet copilot fainted mid-flight from London to Lisbon; paramedics met the plane on landing.
• Former pilots from the US told BI that medical emergencies are routine and procedures are in place.
• Flight attendants are trained in CPR, and airlines are largely required to have defibrillators.

The last thing airline passengers want or expect is for a pilot to have a medical emergency during a flight.

But that's exactly what happened on Saturday when the copilot of an easyJet flight from London to Lisbon fainted while in the air.
