At TFL, we're making journeys safer for everyone, and that includes improving safety on London's roads.

That's why we and London boroughs are lowering more speed limits to 20 miles per hour,

because 20 miles per hour roads have already reduced collisions resulting in deaths or

serious injuries by 24%. That is how we're making journeys in London safer and brighter for everyone.

Such TFL improvement plan to the Mayor of London and TFL every journey matters.

This is CBSI in the world. I'm John Batser from the surface of the planet earth. We're right

there on the surface of the planet earth to celebrate Bob Zimmerman's behind the black 13th

anniversary, and SpaceX has chimed in to celebrate with Bob, because not only 1,9 is made

its 16th orbit, a 16th boost into orbit, but 2 now, Bob, this is to celebrate behind the black.

Everyone's donations and subscriptions are welcome, and now we can watch Bob go for 3 Falcon

Nines to make the 16th trip to orbit. What is this significance of this Bob? How does it

improve things for all launch systems? Just to give some perspective, these two first stages of

Falcon 9, that's two stages of flown 32 times. That's actually more flights in the last 3 years

for those two things, those two boosters, than the entire United States rocket industry launched

annually from 2000 to 2019. In the first two decades of this century, the United States barely

was able to get 30 launches in a year, and these two stages in the last 3 years have now done more

than that, and they basically reduced the cost for launch for SpaceX, probably as much as 90%,

because you advertise the cost over those 16 launches each, and yes, they are going to be more

of a first stage of boosters going to go, that are going to go this much, and those two boosters

aren't done yet, they landed safely, and there's always a lot of them up fly again. So each flight

that costs for the boosters goes down, and the lower launch cost goes down, and I want to

remind people once again that as late as 2016, ahead of Ariane space, that would be impractical
