The Implausibility of Dragons

I don’t know why my brain decided 3 minutes after my putting my head down on the pillow, the other night, to suddenly start thinking about dragons. Specifically, the implausibility of them, as in, just how do dragons breathe fire? 

That question, among many that popped like little soda bubbles, drove me nuts all night long, as I struggled to make sense of just how do dragons fly?

Well, I may not have had a great nights sleep, and it’s taken me a couple of days of pondering, but I’m here now to tell you my thoughts, such as I’m able to wrangle from the wreckage of a night of lost sleep.

First up, lets start with…

FIRE

My logical brain, and the science nerd in me absolutely refuses to believe magic, and magic alone, let alone living in a land supposedly filled with magic is responsible for dragons being able to breathe fire, on command, and—like in certain film scenes where everyone has endless bullets—able to spew fire with impunity. 

I mean, come on people, just how much gas does that dragon have?

Okay, so lets set magic aside, and let’s talk about under what circumstances would a dragon be able to make and sustain fire for any length of time. And here my hat goes off to Anne McCaffrey for her Dragon series, as she—out of all the fantasy books I’ve read over the ensuing decades—at least had a plausible explanation. She got it. She got the gist of what dragons could and should be able to do. In this case, with the Pern series of books:

“…Dragons, bred from small fire-breathing lizards—can breath fire by chewing a phosphine bearing rock called ‘firestone’, which reacts with an acid in a special organ. This forms a volatile gas that can be expelled (at will) and ignites upon contact with the air. The chewed firestone, however, must be expelled from the body after use as the dragons cannot digest it.”

No magic in her fantasy series, but sound logic based on plausible science, that creates a breed of dragon/lizard capable of breathing short bursts of fire. It all makes perfect sense.

Next up, size.

SIZE

How big is too big? I ask because in this next section we’re going to talk about flight, and oh boy, Honey, there ain’t no way some damn wizard or mage is gonna be able to conjure up a spell strong enough to keep a 44 ton dragon in the air for any length of time, without it suddenly and inexplicably falling under the weight of gravity. And that tiny village below? Toast! That dragon is going to make one hell of a mess when it hits with all the power of several MOAB (Mother Of All Bombs)! 

So I think size is going to play an important part in any good fantasy featuring a dragon. To my mind, the Chinese had it right when it comes to shape and size. If memory serves me well, the stories I read as a child had these creatures lithe, slim, long, and lightweight, and I don’t remember any ever flying or breathing fire. I’m not sure where flying came into it with the Euro-version. But let me tell you, even in a world full of magic, gravity still holds sway, and if you are going to put any creature, of any impressive size—and weight—up in the air, you better come up with one hell of a plausible way to convince me this damn thing can fly and, naturally!

Which, I guess, is a good segue into a dragon’s ability to fly.

FLIGHT

I can almost, and I mean, almost believe a dragon could breathe fire, after all, as I said, I’ve read all of Anne McCaffrey’s Dragon series—but flight is one of those magical abilities I have a great deal of trouble getting my logic around. Simply put, as I mention above with size, there’s no way I picture a large several ton dragon taking flight, no matter what length of wing it has. Yes, I know a jumbo jet is heavier, but a jumbo isn’t expected to take flight by simply flapping it’s 200 foot wingspan in order to gain flight. A plane is assisted by 2 to 4 roaring jet engines and a great deal of science, not a pair of leathery wings. 

In my mind I see those large, bulky dragons trying to run along on stumpy legs, furiously flapping their wings while simultaneously jumping as high as they can, to attain flight. But, in the end, are seen crashing awkwardly to the ground in a tangle of limbs an ineffectual wings. Just not plausible.

Now, those small Norse wyrm like dragons of earlier myth, maybe. 

Personally, I think size has everything to do whether or not flight is an option for any self respecting dragon. And for that dragon to take flight, I’m thinking it needs to be no bigger than a large turkey, or bird of a similar size. For me, it’s all about that very important size to weight ratio as to whether or not those wings will get a dragon airborne. 

And you, what are your thoughts?

  1. And poof! the magic of dragons is gone ;-). No my rational side is completely with you, it’s one of the reasons I don’t read fantasy, it’s all just too unreal for me. Love your breakdown!

      Aww, thanks, Inge. It’s good to know there are others like me who feel dragons and that kind of fantasy animal needs to be grounded in some logic if not, science. 😀 I like my magic to have a touch of reality to it.
