When sitting in either jumpseat, you have a very clear view of at least one of the front seat pilots' instruments. In fact, there's not much to do in the jumpseat other than cross-checking the instruments. I'm really stunned that no one caught such a huge deviation from the reference approach speed.

Unrelated, I noticed something I'd never caught before last night. When flying into DAL we flew right over the top of DFW. The terminal layouts are impossible to miss, but all of the runways were a sea of black; even with planes taking off and landing. I take it that the runway lights are louvered so that they're only visible to a plane within an angle relative to the glideslope. Never considered that before. Is that the case laterally, as well? If you're landing on 18R, can you see the lights all the way across at 17L?
Yes, the lights are somewhat directional. Hard to see at all when approaching at 90° to the runway, but plainly visible when well off the extended centerline (not sure of any exact figure, but easily visible at 45°). Similarly, they're hard to see from directly overhead, but when coming in to the runway you can be well above the glideslope and still see them.
When on final for one runway of a set of parallel runways (2 to 4 runways), the other runway lights can be seen when you're out several miles but can be harder to see as you get close in (because the angle at which you're viewing the other runway lights is getting large).
Many civilian fields without control towers have pilot controlled lighting. A frequency is published for these airports and you can turn on the runway lights by quick-clicking your microphone on that frequency. Clicking three times will turn them on at low intensity, five times will set medium intensity and seven times will set high intensity. The brightness can be adjusted by simply clicking again. It was always kind of cool to approach a black hole at 2 a.m. and then see it spring to life when you click the microphone. The lights are on a timer and extinguish again in 15 minutes (iirc).
