In 1995, a 21-year-old electrical engineering student named Mike Marcum called into Coast to Coast AM with an extraordinary claim: he'd built a device that could make objects travel through time.

He'd thrown a metal screw into an electromagnetic field and watched it vanish for a full second before reappearing several feet away.

Mike's ambition was bold. He wanted to scale up the device, make it big enough for a person to step through, and travel to the future to get winning lottery numbers. But he needed powerful transformers—so he stole six from a local power station, causing a massive blackout. He was arrested and spent 60 days in jail.

After his release, radio listeners sent him parts and money to build a bigger machine. In 1996, Mike announced he was 30 days from completion. Then, in 1997, he vanished.

Tonight on Mysteries at Bedtime, we investigate what really happened to "Madman" Mike Marcum.

On March 8th, 2014, Malaysia Airlines Flight 370 departed Kuala Lumpur bound for Beijing with 239 people on board. Less than an hour into the flight, the Boeing 777 vanished from radar screens—and seemingly vanished from the face of the Earth.

What followed was the largest and most expensive search operation in aviation history, spanning years and covering vast stretches of the Indian Ocean. But despite cutting-edge technology, international cooperation, and countless theories, the question remains: what happened to MH370?

This is the complete story of modern aviation's greatest mystery. From the last routine communication with air traffic control to the bizarre sequence of events that followed—the transponder going dark, the dramatic turn off course, the silent flight for hours into the southern Indian Ocean. We examine the evidence, the satellite data, the debris that washed ashore years later, and the heartbreaking search that consumed nations.

Was it mechanical failure? Pilot suicide? Hijacking? A catastrophic decompression? Or something else entirely? We explore every major theory, the facts that support them, and the questions that still have no answers.

Over a decade later, MH370 remains one of the most baffling disappearances in history—a modern aircraft with sophisticated tracking systems that simply ceased to exist, leaving behind only fragments, theories, and the anguished families still searching for truth.
