Highly improbable events are commonplace

In June 2001, on a small farm in Staffordshire, England, a 10-year-old girl named Laura Buxton was celebrating her grandparent’s 50th wedding anniversary. At one point, urged by her grandfather, Buxton wrote a note -- “Please return to Laura Buxton,” along with her address -- on a small card, attached it to a gold mylar balloon, and released it into cloudless sky...
Two days later, 140 miles away in a Milton Lilbourne, a farmer was checking on his cattle in a field and came across the deflated balloon in his neighbors’ hedge. He was about to discard it as trash, when he noticed the note; his neighbors had a daughter named Laura, so he passed it along to them...
The girl the farmer gave the balloon to was also named Laura Buxton, and was also just shy of ten years old... A three hour drive apart, the two Laura Buxtons not only shared the same name, but were nearly the exact same age, were the same height (which was unusual, considering they were both well above average for their age at 4 feet, 7 inches), had brown pigtails and blue eyes, and were in Year 5 in primary school. In a Radiolab interview, the girls recalled the astonishing similarities that arose as they spoke for the first time: they both had three-year-old female black labrador dogs, grey rabbits, and guinea pigs with identical markings (orange spots on hind legs). Upon meeting, they unintentionally chose to wear identical outfits -- a pink sweater, and jeans... You can read the rest of the story at Priceonomics (or listed to that Radiolab story).
