Starship flight 5 caught the booster on the
I already wrote about the catch. But I keep coming back to it. Something about IFT-5 won’t leave my head.
They tried the catch on the first attempt.
Not the second. Not the tenth. Not after a series of increasingly precise near-misses. The first time SpaceX attempted to catch a Super Heavy booster with the Mechazilla arms, it worked.
That’s not how aerospace works. Aerospace works by testing a thing a hundred times before trying it for real. By building scale models and test rigs and simulating every conceivable failure mode. By proceeding incrementally, cautiously, with reviews and sign-offs and redundancies.
SpaceX simulated it, analyzed the data from previous flights, decided the risk was acceptable, and did it.
On the first try.
I think about what that says about their engineering culture. The confidence wasn’t recklessness (the flight termination system would have diverted the booster to the ocean if the approach was off-target). It was a calculated bet that the simulations were good enough, that the hardware was reliable enough, that the software was precise enough.
And they were right.
The margin for error was small. The booster had to be within a very narrow position and velocity window for the arms to catch it safely. Outside that window, the tower and the entire launch infrastructure could have been destroyed.
They bet the tower. On the first attempt.
SpaceX moves at a pace that makes the rest of the aerospace industry look like it’s standing still. That pace comes with risk. But it also comes with results that other companies will spend a decade trying to replicate.
I watched the footage again this morning. For maybe the twentieth time. The booster descending, the arms opening, the catch, the settling. Twenty viewings and my breath still catches at the same moment.
Some things deserve to be thought about more than once. This is one of them.

- Starhopper flew and it looked ridiculous
- Starship SN8 flew 12.5 km and then exploded. It was beautiful.
- SpaceX landed Starship for the first time and I yelled alone in my apartment
- Starlink has 2,000 satellites and I can see them from my roof
