Pigs Can’t Fly: The Peculiar Reason KLM 787-9 Diverted To Bermuda

By

Six hours into a KLM transatlantic flight, the captain radioed air traffic control as the aircraft approached Bermuda with a strange request: we need to divert because of the pigs onboard. And no, the captain was not referring to unruly passengers.

KLM Flight Diverts Due To Stench From Pigs Onboard

KL685 was traveling from Amsterdam (AMS) to Mexico City (MEX) on December 13, 2024 on a Boeing 787-9 Dreamliner aircraft. There were 259 people onboard…and 100 pigs in the cargo hold. Per the captain, the pigs began to stink…creating an “obnoxious smell” in the cockpit.

The ATC is fasciating (fast-forward to the three-minute mark if you want to get right to the pigs):

The flight landed in L.F. Wade International Airport in Bermuda (BDA) after dumping fuel. There was no declared emergency: just a bad smell.

With the unintended stop, the flight was unable to continue to Meixco City that day, thus overnight accommodations had to be arranged for the pigs onboard…and the 259 passengers as well.

Passengers were placed in hotels while KLM worked with the Bermuda Government, Menzies, Delta Air Lines, and Skyport to find “humane” lodging for the pigs.

The next day, the light continued to Mexico City without incident.

How Could This Happen?

I’m not sure why pigs were flown from the Netherlands to Mexico in the first place (unless it was a bunch of fertile females ready to help Meixco increase in its pork population), but I do have a question. Doesn’t the cockpit receive fresh air from outside? The 787 Aircraft Operations Manual (AOM) states:

“The flight deck receives 100% conditioned outside air and the passenger cabin receives a mix of outside air and recirculated air.”

So was this really pigs making the stench or just one of the relief pilots reacting poorly to a fish dinner?

I somewhat jest, but it is a serious question…how does the pig stench reach the cockpit?

CONCLUSION

A KLM 787-9 diverted to Bermuda after a strong pig stench onboard. This has to be one of the oddest diversions I have ever seen…and it had nothing to do with passenger beahvior. It still isn’t clear to me how the odors from the cargo hold entered the cockpit, but I’d imagine it must have been very bad in order to make a very costly diversion.
