proper positioning usually ends up saving time (and bad outcomes)
do not intubate in this position

start laryngoscopy early
goal: one millimeter per second
optimal conditions not at the start, but at the end of laryngoscopy

use a bougie
would you rather throw a basketball or a baseball through a basketball-sized hole? coudé tip
it is easier to intubate with a bougie than with an endotracheal tube
