There was a story about a car crash in Israel where the chiloni driver was declared medically dead when they pulled him out of the wreckage. Suddenly, and old man with a long white beard appeared in a tallis, and began MTM resuscitation on the “dead man”, who spluttered back into life.
When they turned to thank him, he had disappeared.
Everybody thought it was Eliyahu Hanavi.
In reality, it was the Hatzolah guy from down the road, on the way to Shul for Shabbos morning Shacharis.
I love this story.
