This story is not about a miracle, or a holy person, it's just about someone wanting to do a mitzvah, and having tremendous help from Hashem.
My neighbor here in Ramat Beit Shemesh has a 'gmach', a chessed project, where she lends out baby swings for people with newborns. Her mother buys them at closeout places in the US and then sends them whenever she can. The latest find, a windup baby swing that is no longer manufactured and is in high demand for its convenience for use on Shabbos and Yom tov, was stuffed in a huge oversized duffel bag, waiting for a 'ride'. My friend's mother went to a wedding and met someone from Israel who had flown in just for the simcha. He was flying back that night. She asked him how many suitcases he had with him, and when he told her had only one, she said, "Great so you'll take a baby swing for my daughter's gmach. It's in a huge duffel bag, but from my experience, when you bring things to Israel for a mitzva, they get through."
Well, he shlepped that oversized bag to the airport. It didn't fit on the conveyor belt, and they had to call in special airport personnel to figure out how to get it on to the plane. But no one said a word to him about paying a fine or leaving it behind, ad the swing made it's way here without a hitch!
If you do your part, Hashem will do His!
