The consortium also considered other noise reduction technologies such as a trailing edge with optimized "Krüger flaps" or modern geared turbofan engines with a large ratio of the airflow outside the combustion chamber to the airflow of the hot exhaust jet, which significantly reduces noise.

“The combustion chamber burned for 10 seconds, marking engineering progress but also demonstrating liquid biomethane as a sustainable rocket fuel, Interstellar representatives said in a Dec. 7 statement. The Zero rocket will notably use liquid biomethane fuel produced locally from livestock manure — cow dung — with liquid oxygen as the oxidizer,” Space.com said.

From Washington Times

In March, Blue Origin said New Shepard would fly "soon" after concluding the mishap was caused by a "structural failure" in the rocket's engine nozzle, which had been contorted during flight by hotter-than-normal temperatures coming out of the engine's combustion chamber.
