Plane took off about an hour ago. 5 minutes later, we were allowed to go outside. Internet was switched off but is now back on. Everything back to normal. I suspect we may find out tomorrow (on North Korean media) who visited Wonsan and why we had to stay inside for a few hours. https://t.co/gFYFugRZry
