Inanimate manifestations ...

Not all ghosts are animate in nature. Inanimate objects such as ships, trains, automobiles and aircraft have been regularly reported, and remain among the most difficult type of manifestation to account for.
Obviously, since inanimate objects do not possess consciousness and were never 'alive' in any sense of the word, their 'survival' after their demise seems to have no rationale.
The best answer is that they are not actual manifestations of physical energy at all, but mirages or pre-recorded impressions of some kind, making them more akin to the 'imprint' variety of ghostly manifestations than anything else.
The difficulty with this theory, however, is, as we touched upon a moment ago, the lack of environment upon which to imprint the object. A 'ghost airplane'—for example—could hardly have been somehow imprinted upon the currents of air in the same way a person might be imprinted into the building material of a house. Air is not a stable medium like a solid object, making such a phenomenon all the more inexplicable (the same is true with 'ghost ships' as well, with the ever changing sea being a logically unlikely medium upon which to hold and replay the image of a ship.)
In any case, inanimate manifestations (sometimes also called apparitions) are uncommon and tend to be non interactive (though not always.) They are also usually 'one shot' affairs that rarely repeat themselves, making them difficult subjects to study or document. However, there are a few exceptions: long ago fought battles are reported to sometimes appear repeatedly, or at least the noise of that ancient battle is heard still rumbling off the horizon.
Whether this is some kind of imprint or an example of a 'time slip' (an idea we will examine in more detail later) is unclear.
