Maury Island Mystery: UFO Debris, a Man in Black, and the FBI's Hoax Conclusion

To the point

Before Roswell, Harold Dahl and companions on a Puget Sound boat reported six donut-shaped flying objects whose debris injured his son and killed the dog; a man in black warned him not to talk, two officers who collected the debris later died in a plane crash, the FBI called it a hoax by Dahl (which he said was to avoid harassment), conspiracy theories link it to Hanford waste with no credible evidence, and it inspired the 1997 film Men in Black with Will Smith and Tommy Lee Jones.
