A classic example of good videolaryngoscopy technique being thwarted by not always using an introducer (stylet or bougie).  Note the clinician performing the intubation gets perfect, optimised VL view (Rule of 3), but then struggles to pass the ETT anteriorly enough, losing time.  Although this was no problem for the well-oxygenated patient in this case (and the intubation is still under 45 seconds duration), in a critical case it can lead to desaturation, frustration, and possible intubation trauma.
