Telemetry lost at T+6:51 with vehicle rapidly dropping before that. Arianespace CEO claims second stage underpressure issue.

Yep confirmed here. Underpressure in the 2nd stage. Either a failure to ignite or an underperform. Either way a launch failure. Apogee was 110km and vehicle impacted Atlantic Ocean shortly after.

The ground camera says it lit. Remember 2 failures ago, when it burned through the top of the 2nd stage? This is a different stage (wider). But still.

It looked like it lit, burned a while, then something happened that caused the plume to become much wider and more diffuse, and the stage was either gyrating or tumbling. Maybe a major failure of the nozzle?

That’s what I was thinking. Either they burned through it or the back fell off. Either way they lost command authority and thrust.

What about the front?

Well it’s not supposed to fall off, I can tell you that right now.

It seems like the third stage separated and ignited normally, and that's attached to the front. Maybe it broke away before that though, the CGI was obviously not an accurate depiction of what was going on.

Probably something like that. You can see the speed start to drop right then, too.

At least they made it to space, although I don't think the satellites were supposed to end up at the bottom of the ocean.

This is a good example of why most people think "space" means "orbit".

The Karmen Line, which is what I was going off of, is arbitrary with some aerodynamic calculations to back it up, it’s much easier to to define what an orbit is rather than where space begins.
