Por que falhou o "Concordovsky"? O Tupolev 144 até começou a voar alguns meses antes do Concorde mas como sabemos a pressa nunca é boa conselheira. O avião revelou desde o início grande instabilidade a voar a baixa velocidade o que levou à adoção de dois canards (aquelas "asas" junto ao cockpit) que eram usados durante a descolagem e aterragem. O TU 144 era até mais rápido que o Concorde, voava a Mach 2.15, mas só conseguia manter voo supersónico com os afterburners (pós combustão) dos motores sempre ligados o que provocava um enorme consumo de combustível e evidente redução de autonomia. O Concorde só usava afterburner para atingir velocidade supersónica, Mach 2.04, que depois mantinha com os motores em regime de cruzeiro normal. O Concorde tinha travões com discos de carbono nas 4 rodas de cada trem principal enquanto o TU tinha 8 rodas (12 nos aviões de teste) em cada trem equipadas com discos de aço. Usava habitualmente um paraquedas para ajudar na travagem. Os motores Rolls Royce Olympus do Concorde tinham reverse (inversão do fluxo de gases de escape) ao contrário dos Kuznetsov do TU 144 que não estavam preparados para tal. Os Tupolev 144 fizeram apenas 55 voos comerciais com passageiros enquanto os Concorde fizeram milhares de voos ao longo de uma carreira que durou mais de duas décadas. Ambos sofreram acidentes fatais

El transbordador era una máquina prodigiosa, pero demasiado cara; costos que se multiplicaron tras la explosión del Challenger. Igual para las nuevas generaciones resulta increíble que hace 40 años teníamos un avión que iba al espacio.

Space Shuttle Discovery lights its main engines on the pad, then sits there for about 6.6 seconds before it's allowed to leave.
The sparks at the start burn off loose hydrogen under the engines so it doesn't ignite in one big bang. Then the three main engines start, and the computers watch the thrust build. Only if it all looks right do they light the boosters and blow the bolts holding it down.
That order is on purpose. The main engines can be shut down on the pad. Once the solid boosters light, nobody can stop them.

✈️🫨 Lors de son dernier vol libre, la navette spatiale Enterprise connaît un atterrissage mouvementé. L’appareil arrive trop vite, les corrections de pilotage déclenchent des oscillations induites par le pilote. Enterprise rebondit sur la piste mais l’équipage stabilise l’engin.

🚀🇺🇸 Il y a 49 ans ce jour, le 26 octobre 1977, la navette spatiale Enterprise réalisait son cinquième et dernier vol libre à la base aérienne d’Edwards. Larguée depuis un Boeing 747, elle planait avec succès, concluant une série d’essais essentiels au programme de la NASA.

Veteran astronauts Fred Haise and Gordon Fullerton completed the fifth and final glide test aboard Enterprise OTD in 1977. The Approach and Landing Tests (ALT) took place between February and October 1977 to test the Shuttle's flight characteristics prior to its first spaceflight in 1981.

What did it take to move a legend?
From restoration and demilitarization to carefully loading it aboard a C-5M Super Galaxy, this is a behind-the-scenes look at the journey that brought the F-117 Nighthawk "Overachiever" to its permanent home at the National Air and Space Museum’s Steven F. Udvar-Hazy Center.

24 October 2003. Last commercial flight of the Aérospatiale-BAC Concorde. At 4:05 p.m. BST British Airways Concorde G-BOAG landed at Heathrow Airport, third in sequence with G-BOAE and G-BOAF after all three had made low passes over London.

This is your periodic reminder that when the Soviets didn't have an aircraft large enough to carry and drop their Buran prototype like NASA had done with Enterprise, they just added turbojets and made OK-GLI take off under its own power.

13 October 1950. First flight of the Lockheed L-1049 Super Constellation. American four engine airliner with lengthened fuselage, strengthening for higher gross weight, increased fuel capacity and more powerful engines. Accommodate 71 first-class or 95 coach-class passengers.

This F-117 Nighthawk was loaded aboard a C-5 Galaxy and transported to the National Air and Space Museum, Smithsonian Institution . 💙💙💙
The aircraft is currently in the Mary Baker Engen Restoration Hangar, having its wings reinstalled before it goes on public display.
