One of the best-documented cases of bilocation was that of Mary of Agreda, who in the 1600's bilocated in Texas/New Mexico while never leaving her native Spain; historian William Carroll says it is completely inexplicable outside of supernatural intervention.
I found some of the bilocation experiences.
One of the incidents I remember hearing was at Communion a woman was kneeling at the far end of the rail and looked up to see Padre Pio offering the Eucharist, which she took, but she was startled because he was also at the other end of the rail at the same time giving Communion.
The other was the Nazi bombers who were over his town and were frightened to see him in the air, so frightened they turned around and went back to their base.

Here’s another:
“As documented in a solidly researched book, Padre Pio: The True Story (by an initially skeptical Protestant minister), there were accounts that defy the belief of even the most ardent believer: a sighting of him at the Vatican even though he never left the San Giovanni monastery; the transfiguration of his face into that of Jesus’ during consecration; a worker named Giovanni Savino who lost an eye that later materialized under the bandages after Pio visited him in bilocation.”

There is also the dying teen in a Pennsylvania hospital who woke and spoke about being visited by St. Pio who came into the room and patted his hand and talked to him.
He’s an extraordinary saint. Of course, all these great followers and friends of our Lord are.
