This happened before inventing the planes so what could have been there(it’s proofed that something crashed there). Also it appears that there exists a well where were threw a part of the remainders of the aircraft and it looks like the ’‘alien’’ was buried in cemetery.In 1970’s a team of UFO specialists investigated the town and the localized the alien grave (marked with a small stone with an aircraft on it) but they didn’t obtain the right to dig there,also for a period of 2 weeks the police secured the cemetery and in this period the stone and the metals that were inside the grave(they scanned the grave and the crashing sight with a metal detector and they had the same signal in both places).What do you think about all this?Do you think that is a real story?Do you think that in 1970’s someone hide the evidences?
