Skythrust is a supersonic airliner. Like the Fireflash airliners, Skythrust has a freight deck for cars and other various cargoes at the rear end of the aircraft.
It is considered one of safest airliners in the world due to the 'Hackenbacker' fuel pod. How does this 'Hackenbacker' fuel pod make it safe? Well, if Skythrust needs to make an emergency landing, the fuel pod can be ejected upon landing and a fuel flow regulator on-board Skythrust stops the fuel from going to the feed pipes. However, low fuel capacity engines means Skythrust could be brought down to land if the fuel pod is ejected in mid-air. After the 'Hackenbacker' fuel pod is ejected, it can be self-destructed at a high, safe altitude or taken down to the Earth, in a safe descent.
It only appears in Alias Mr. Hackenbacker.
At the start of Alias Mr. Hackenbacker, a D103 airliner is coming in to London Airport for an emergency landing, due to a landing gear failure. London Airport evacuates the area and sends in ambulances and Crash Tenders in an attempt to save the lives of those on board, but the aircraft catches fire as it crashes and the craft violently explodes due to the fuel tank catching fire. Sometime after, Brains, operating under the name Hiram Hackenbacker, developes a device that could improve its safety.
However, instead of giving it a simple refit, Brains completely redesigns the airliner. On board the new aircraft, named Skythrust, on its maiden flight from London is Lady Penelope and a French fashion designer, François Lemaire, who is ready to reveal a new clothes fabric that can make dresses fit into spaces as small as cigarette boxes. However, the plane is hijacked by Francois's assistant, Madeline, and Mason, the steward, who demand the pilot, Captain Ashton, and his co-pilot, to fly to the Sahara Desert in Africa and land there. Lady Penelope calls International Rescue and orders Alan and Virgil following Skythrust in Thunderbird 2 to fire a non-explosive missile at the planes landing gear which causes a fault in the landing gear. Realising that there is no airport in Africa that is suitable enough for Skythrust to crash-land, the hijackers order the pilots to fly back to London Airport and crash-land there. With all the Crash Tenders in position, Skythrust approaches the airport and just before crashing, its new device is revealed to be a ejectable fuel tank, thus allowing the aircraft to crash-land without bursting into flame, saving everyone on board.
Brains had saved the day.
