Kaifeng fireball and fragment

Residents and officials in Kaifeng and nearby counties saw a large fireball cross the night sky, and the next day the press reported an unidentified flying object. A fragment reportedly fell into a residential compound, damaging a tree and a bicycle; it was shown publicly, and government analysis found it to be an aluminium-magnesium alloy and ruled out an extraterrestrial origin, without identifying what aircraft or spacecraft it came from. Later stories of a household illness and an alien cure are part of the local lore, not of the record.

Re-entering artificial debris or a bolide; the fragment's source was never identified
