OBD: as Jwscud stated, about a 2.5 degree pitch change and if you don't anticipate or perhaps are pushing the nose down while making that change. . . .
Flyingchanges: I suppose about 12 MPH overtake could feel like you are being passed like you're standing still, right?
Seriously, I'm sure there are some guys who do "speed", but not as many as people think.
747Flyer: Sorry, no clue. Burbank was before my time here and I don't know if that aircraft had a HUD or not. As for the LGA incident? Don't know, not going to guess. The HUD is not required to be used during every approach, and since this was a visual approach, don't think too many Capts would bring it down. (For those not familiar, on SWA jets, HUD is installed only on the Captains side.
