As mentioned in different hadiths description of Dajjal's donkey I don't have all the references but one of them is as follows from Kanzul-Ummal,vol. Vll, p. 267
The Dadjjal`s donkey will travel on water as on land. Traveling on land it will have clouds both in front and behind
Also mentioned in other places that the dajjal's donkey will be so big that it will have a large gap between his ears and have opening on sides and people will sit in it. And it will eat fire and it won't burn people sitting in it. It will have comfortable places inside and lighted from within, and people will travel in it. And the donkey will belong to dajjal. And the donkey will be so tall that his head will be beyond the cloud lines. And also mentioned that it will stop at different stages and make announcements.
By travel on water can this be associated to ships.
According to above description can one take the meaning of donkey as an aeroplane. As Plane has jet engine which emit fires and people sit inside it and there are announcements made before it takes off and it travels above the cloud lines. It makes more sense when taken metaphorically and if taken literally it doesn't seem possible for such a huge donkey to exist and doesn't even make any sense. Seems more like a fiction story.
Is this concept valid and if not then what are the obstacles behind it.
The link from where I have taken the concept from is below: https://www.youtube.com/watch?v=LZqqm-M7HBA
