Charles Manson claimed to levitate a school bus in order to get it to the group's hideout at Barker Ranch in Death Valley in 1968. His followers claim he did it, too.
We know the school bus got there, because it was still there until a few years ago. The terrain up Goler Canyon Road is very difficult even for four-wheel drive vehicles.
I don't believe Manson levitated the bus (or that there was a single tree that bore twelve kinds of fruit, one for each month of the year, at Barker Ranch, as he also claimed). Do you?
There are also numerous eyewitness reports of remarkable phenomena, including levitations, occurring at Spiritualist seances. However, the most exhaustively documented ones show that eyewitness testimony is at odds with what actually happened--a phenomenon that magicians are quite familiar with. If demonic activity results in such things as levitation, why is it not documentable through video recordings or testimony from witnesses trained in illusion and trickery?
