liftoff

What happens if a pressure sensor in one of the tanks fails a second after liftoff?

More warp (warmth) is the gap in sound as the needle achieves that coveted liftoff effect.

And now you have to accelerate twice as much mass at liftoff requiring even more fuel.

Same here, but they said the liftoff was nominal so I'm guessing it's either imagination or camera angle.

They arm it before liftoff and disable it after it's well over the ocean.

Did anyone else notice how fast the Vega liftoff was?

I imagine the cost-benefit analysis changes when liftoff is nearly impossible with available chemical rockets, though I'm not quite sure what your objection is.

In case it wasn't clear there, the real challenge here is using something that wasn't designed for landing - it was designed for liftoff - to do the landing.

But that's really limiting the scope of who's going to get involved, and it's probably going to make it harder to get a sufficient community involved to help your project achieve liftoff.

STS-27 in 1988 sustained very severe tile damage from a foam strike during liftoff (around 700 tiles were damaged, including some which were completely destroyed), which resulted in partial melting of some of the airframe components during re-entry.

The very first flight of the Shuttle involved an "anomaly" during launch which the crew said would have resulted in them attempting to ditch if they had known about it during liftoff.

Suppose I take a bird or deer strike just after liftoff that damages the propeller and the "squat switch" (the weight-on-wheels sensor that prevents the gear being raised electrically).
