“Connor Broekhart was born to fly, or more accurately he was born flying.”

“In the lost battle,
Borne down by the flying,
Where mingles war's rattle
With groans of the dying.”

“"Man is born unto the trouble as the sparks fly upwards." In other words suffering is germane to our existence; indeed, how without it, should we be able to "fly upwards".”

“O human race, born to fly upward, wherefore at a little wind dost thou so fall?”

“When a man is born… there are nets flung at it to hold it back from flight. You talk to me of nationality, language, religion. I shall try to fly by those nets.”

“He who would learn to fly one day must first learn to walk and run and climb and dance; one cannot fly into flying.”

“Orr would be crazy to fly more missions and sane if he didn't,
but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. That's some catch, that catch-22.”

“To fly or not to fly, that's the question.”

“Right. Vampires. But how do they get inside?"
"They fly"…
"We dont fly," Clary felt impelled to point out.
"No," Jace agreed. "We dont fly. We break and enter."…
"Flying sounds like more fun."
-Clary & Jace, pg.258-”

“Call the sun in the dead of the night
And the sun gonna rise in the sky
Touch a man who can't walk upright
And that lame man, he gonna fly.
And I fly, yeah, And I fly.”
