Crashed drones programmed to fly from North Korea and back - South Korea

SEOUL (Reuters) - Three drones that crashed in South Korea had onboard flight programming that showed they were launched from North Korea and were meant to return after flying over military installations in the South, the defence ministry in Seoul said on Thursday.

South Korean and U.S. officials jointly examined the three drones that were recovered in three different locations near the Korean border over a two-week period starting in late March.
