In April 1942 the Air Force configured a Douglas A-20A Havoc to demonstrate two 1,000-lb-thrust liquid-propellant JATO units mounted in the engine nacelles for shorter takeoff runs and improved performance. The A-20A completed 44 successful firings with no stability or control issues.👀

Beijing continues to push boundaries — the modernized carrier rocket “Zhu-que-2E” with two communication satellites has been launched, announced “Xinhua” It uses liquid oxygen and liquid methane as propellant, and the special significance of this project lies in the fact that this is the world’s first rocket to use methane fuel and successfully reach orbit, representing an important step in the development of a new generation of space launch systems.

As a droplet touches a liquid surface it bounces gently, kept afloat momentarily by a thin air cushion. As the air dissipates the droplet comes in contact with the liquid. The droplet undergoes a multi-step coalescence journey: with each interaction, it merges and reduces in size, transitioning into a smaller droplet, until it eventually fully merges with the liquid below.

The Avro York first flew July 5, 1942, a British transport using Lancaster bomber wings, tail, and 4 Merlin engines with a boxy fuselage. 258 built, it hauled 56 passengers or 16,500 lb cargo, served as Churchill’s VIP plane, and flew thousands of tons in the Berlin Airlift.

Never forgive. Never forget. They knew what they were doing. Bosnia, April 1996. In a classroom of 26 students, 20 are refugees from Srebrenica. The teacher asks, "Who has lost their father?" 18 hands go up.

🚀 Starship will be the 1st fully reusable orbital rocket in history. Liquid oxygen, liquid methane, and a cost-per-launch that could drop below trans-oceanic air freight. Elon put it simply: "The cost of access to orbit is just the cost of propellant." If that holds, the economics of space will get rewritten entirely. Source: SpaceX, Elon Musk
