Naturally, the social media-happy stars documented the incident every step of the way. Though their chopper had to land on a golf course, Kim and Kourt didn't seem particularly concerned, Snapchatting the entire time.
"Emergency landing on the golf course," Kim said in the clip, while wearing a giant fur coat.
"Stay calm," Kourtney adds.

The pair then gave fans an update, showing the pilot, closing the helicopter's doors.
"We found the problem!" Kim declares. "A seatbelt was hanging out that was making a rattling noise."
And with that the family and their pals were free to enjoy their Iceland getaway.
This isn't the first time the famous family has found themselves in a scary situation while on vacation. Last year during an outing in Montana, Khloe Kardashian hit some ice on the road, causing the car full of stars and their kiddos to slide into a ditch.
Monday was Kourtney's 37th birthday, and the group celebrated with several cakes, a fun day out in the snow, and trekking to a beautiful waterfall, which was all documented for Keeping Up With the Kardashians.
"That's so pretty," Kim narrated one clip. "Midnight waterfall run."
Kim's hubby, Kanye West, was also present, giving his wife a smooch in the snow in another Snapchat video.
The group has been enjoying their overseas adventure, while younger sisters Kendall and Kylie Jenner party with Kourtney's ex Scott Disick at the Coachella Music Festival.
Disick took the time to honor his former flame's special day on Instagram, posting a steamy make-out photo of them with the caption, "Happy birthday @kourtneykardash everyone who knows you loves you so much!"
