Ten minutes might not seem long – unless you’re in the air with no conscious pilot in the cockpit. That’s exactly what happened on a Lufthansa flight last February.
The flight from Frankfurt to Seville started like any other. The captain got up to use the bathroom, leaving his co-pilot in charge – a routine practice in commercial flights. Then everything changed.
The 38-year-old co-pilot suddenly had a seizure and blacked out. Just like a driver fainting at the wheel, but in this case, at cruising altitude in an Airbus A321. The difference? The plane’s autopilot kept everything steady, like an invisible hand holding the controls.
The captain couldn’t get into the cockpit. He punched in the security code – not once, but five times. Nothing worked. A flight attendant tried calling into the cockpit. No answer. The security door, built to keep hijackers out, was now keeping the captain out too.
“Strange noises” came from the cockpit, picked up by the plane’s voice recorder. These sounds told the story of a medical emergency unfolding behind the locked door.
The captain had one last option – an emergency code he’d learned just a month before in training. But before he could use it, the co-pilot woke up enough to open the door. What the captain saw wasn’t good: his colleague was pale, sweating, and moving strangely.
Lucky for everyone, a doctor was on board. While the doctor helped the sick co-pilot, the captain made a quick decision. Madrid was the closest airport, and that’s where they headed.

All 205 people on board – 199 passengers and 6 crew members – landed safely. Later tests showed the co-pilot had a hidden brain condition that could cause seizures. No previous medical check had caught it.
The Spanish investigators looking into the incident found the plane’s autopilot did its job perfectly. But they raised a big question: should airlines always have two people in the cockpit? It’s like having a backup driver – if one person has a problem, the other can take over right away.
Lufthansa knows about what happened. They’ve done their own investigation but haven’t shared what they found. Meanwhile, European aviation safety officials are taking a hard look at current rules.
This close call shows how modern planes can practically fly themselves in an emergency. But it also reveals a gap in safety rules. What good is a secure cockpit if it keeps help out during an emergency? It’s like having a vault that’s so secure even the bank manager can’t get in when needed.

The European Union Aviation Safety Agency now wants all airlines to know about this incident. They’re asking everyone in the industry to think hard about their safety rules – especially about leaving just one pilot in the cockpit.
The happy ending here – everyone walked away safe – shows how well aviation safety systems can work. But it also reminds us that even the best systems need regular updates. After all, in aviation, there’s no such thing as being too safe.
