THIS IS NOT A SONIC BOOM Okay folks, it’s been long enough. Time to finally address the biggest point of confusion on #AvGeek twitter: what exactly is going on with vapor cones? Let’s just say much of what you’ve read is (probably) wrong. Wonder no more: a thread... 1/n
SKYLON IS BACK BABYYYY GIMME MORE SPACEPLANES
🚀Meet INVICTUS – Europe’s new hypersonic test platform. We have joined forces with UK-based Frazer-Nash to kick off INVICTUS, a research programme with the goal of developing hypersonic technologies applicable to future reusable vehicles capable of horizontal launch. Learn…
"Clouds are a scary conspiracy" might be the dumbest trend I've ever seen on this site and has me thinking we should maybe just delete the internet

I'm not saying it's for sure the SR-72 but like come on

Now try doing this to an F-35
When someone brings a jammer to a drone show:
Imagine launching a cruise missile from a Piper Navajo Lockheed is trying to make your dreams come true

Put simply there is a lot happening here
There are take-offs, flamboyant take-offs, very flamboyant take-offs… and then there is whatever this Finnish F-18C Hornet is doing 😳🔥
RIP to the most aerodynamic of dudes

Absolute peak engineered performance

Around a 20% cut for science and flat top-line (compared to the previous ~50% science cut) Far from perfect but a huge improvement over the devastating presidential budget request
House appropriators have released their draft CJS spending bill. Overall NASA funding is kept flat vs FY25 at $24.8 billion; however, exploration is increased at the expense of some cuts to science, space tech and other accounts. appropriations.house.gov/sites/evo-subs…
For real though how many times does Falcon 9 get to fly its 500th mission
Falcon 9 completes its 500th mission
Either the speed of light is really fast or we are really slow
I am currently ~19h 19m 28s of light travel time from Earth (2025:193:000000:2L)
