not what i thought

Flickering along just out of sight,
A dragon flew by me last night;
His wings overhead
May have filled me with dread,
But at least he neglected to bite.
-
The dragon's incessant and arrogant shriek
Left me feeling confused and frightened and weak.
As his drone disappeared,
It was just as I'd feared:
To the airfield he turned as his landing gear squeaked.
-
Flaps down, he cried to the tower, at last,
And I ducked as his tail fin's shadow flew past;
This mythical creature, I see now, it's plain,
No dragon at all, is a small private plane!
I stand, shaking slightly, still staring, aghast.
