That was great. Right about that thrust:weight ratio though. Seemed to take an age to clear the tower.
General view is that the TWR was around 1.1/1.2 - and that with a light payload. Probably wouldn’t have survived even a single engine failure at lift off.
Not sure if they deliberately had the engines throttled back to reduce loads on the second stage or had a more generic issue. But seeing as their planned payload is only about 45T, they’ll have to work to generate more thrust in future.
