On a family trip 30ish years ago I "accidentally" dropped one down the face of Hoover Dam. It took one bounce about 100ft down and disappeared. I like to imagine it ricocheting down the canyon all the way to Mexico!
Titan rockets made beautiful blue ones! Titan's main engines burned hydrazine and nitrogen tetroxide, making for a nice light blue color. SpaceX is using the much safer liquid oxygen and kerosene. They can also often be seen in jet engines with afterburners in use, shown here: [upload.wikimedia.org]
A bit off topic, but this reminds me of an old friends dumb joke - Why do rednecks drive Fords? Because when you're drunk, it's too hard to say chebro...shib...chever...aww screw it.
A very useful feature if you ask me. During rural driving where the only light is from your headlights, a brightly lit interior makes it harder to see to the edges of that light where nasty things like deer, downed trees and missing pavement hide.
34°35'01.46" N 120°11'37.22" W - Plug this into your streetview. The northbound one is the bridge in question. Trying to hit this narrow piece of crap at 70-75mph (normal traffic speed through here) can be a challenge. It's on a downgrade and a curve and you can pick up a bit of speed if you're not paying attention. People tend to suddenly slow down when they see how narrow it is. The three sets of bridges through here are probably unchanged since the 50's and are obviously dangerous. Maybe this tragedy will prompt the state to improve or replace them.
