Malheureusement c’est exactement ce qu’il s’est passé pour la navette Challenger en 1986… Peut être qu’on a appris de cette erreur :)

I was curious about the number of passengers carried by rail, so I looked at the wikipedia page. The US is 12th with 533 million passengers in 2019, which I find surprisingly low when compared to the population/size of this country. In France, same year, there was 1880 million passengers. I don’t think the rail infrastructure is well developed in the US, probably to the benefit of car infrastructure.

lol, I would do it to, can you make an article about me then ?

I use perlite to improve the drainage of the soil of my houseplants, I did not know it was used in construction and it was such a big market. So I was a little confused.
