Mid-April 2013, the low air pressure above the clouds surrounded a helicopter and its accompanying UAV escort. Mr. Lee and his family sat in their seats uncomfortably. The helicopter provided luxurious amenities, but it was the sense of unknowing and confusion that unnerved them.
The strange and mysterious men who brought them from Seoul never answered any questions about why they had to go to North Korea, of all places.
The air pressure began to rise as their vehicle landed within a remote helipad among the blooming cherry blossom forest. Then, finally, the platform started to move and lowered itself underground.
Mr. Lee felt relieved to see the men in black didn't send them to Pyongyang.
He walked out of the helicopter and was amazed to see a massive underground facility. His family followed and stared in awe, watching manufacturing drones, engineers, and armed security working around the area.
