Brennschluss

noun1

1. •
   The moment in the path of a rocket when the fuel burns out, after which it continues its ballistic trajectory under only the forces of gravity and air resistance (if present).

   • The white line, abruptly, has stopped its climb. That would be fuel cutoff, end of burning, what’s their word... Brennschluss. We don’t have one. Or else it’s classified. — 1973
