The internet at large has been ablaze recently with stories about a radio-controlled scale model of a World War II German King Tiger tank whose job was to drill holes in over-pressurized Space Shuttle tires during ground tests. Now, whether a Second World War German tank serving as the basis for this vehicle has any explanation other than NASA engineers being the most lovable dorks in the Milky Way or not is up for some debate. But mixed up in the social media circus is the aircraft wearing these special tires so brimming with PSIs that it'd kill anyone within a radius of a few dozen feet. This is the story of the Convair Coronado, a failed commercial passenger jetliner that had a miraculous second renaissance working for NASA. Only then did it receive the above-mentioned RC Tiger tank robot buddy we all know and love. But at the start of the program in the late s, Convair genuinely wanted to re-invent the wheel with the jet. At the time, American Airlines, in particular, was extra keen on a long-haul, narrow-body jetliner capable of flying across the Continental U.

The Convair Coronado was an American narrow-body four-engined jet airliner produced between and by the Convair division of American company General Dynamics. It was a stretched version of its earlier Convair produced in response to a request from American Airlines : the was lengthened by 10 ft 3. American Airlines asked Convair to design an aircraft for coast-to-coast flights, able to fly nonstop from New York City to Los Angeles against the wind. They wanted a larger passenger capacity than the , which was the smallest of the first-generation U. It was known as the Convair and was redesignated the Convair in the month of its first flight. One change from the was the large anti-shock bodies on the upper trailing edge of the wings, to increase the critical Mach by reducing transonic drag. The inboard shock bodies, which were larger, were also used for additional fuel tankage. Later during the design period, Convair modified the design to include fuel in the outboard pods as well, but during the initial test flights the extra weight caused the outboard engines to oscillate in certain conditions. The pods were redesigned once more and shortened by 28 inches mm , causing increased drag. The inner set of pods were used to route the fuel-dump tubes from the fuel tanks, terminating in a prominent outlet. The engine was a simplified, non-afterburning civil version of the J79 , used in supersonic military aircraft. Like most versions of the J79, the CJ and CJ were smoky, although secondary operator Spantax eventually had their engines refitted with low-smoke combustion chambers in the s.

Based in Liverpool, United Kingdom. To accommodate a higher number of passengers, Convair elongated the jet ten feet, allowing it to carry between and passengers.

The Convair was designed to surpass its competition in coast-to-coast flights. It was fast but only 37 were sold, making it arguably the most unsuccessful aircraft in history. Yet, its legacy inspired commercial aviation for decades to come. Keep reading about the Coronado and one in particular that has some interesting stories to tell. It is a stretched version of the Convair , longer than the by 10 feet and capable of carrying 96 - passengers.

The Coronado is gradually being restored. Gabriel Alomar. In the airline Spantax ceased operations. A Convair CV Coronado , the only surviving plane from the airline's fleet, has been at Son Sant Joan Airport ever since; it has been parked in the airport's military zone. The Friends of Son Sant Joan association has been instrumental in the plane's restoration. Some of its members have been to see how the work is progressing. Some glass needs replacing, as do the tyres. The engines are intact but they are affected by rust. However, part of the exterior has been newly painted with Spantax colours. In the cabin, the seats have been re-covered and curtains put in by the windows.

The Convair has its roots in the manufacturer's series. London: Samson Low, Marston, While many aircraft came to the market during the 50s and early 60s, two significant rivals were the Boeing and Douglas DC-8, two quad-engine jet airliners.

On 5 January , a Convair Coronado operated by the Spanish airline Spantax crashed shortly after take-off from Stockholm Arlanda Airport , killing five of the ten people on board.

Proctor, Jon. With a cruising speed of Mach 0. Later during the design period, Convair modified the design to include fuel in the outboard pods as well, but during the initial test flights the extra weight caused the outboard engines to oscillate in certain conditions. The was produced to meet an American Airlines request for a plane that could fly from New York to Los Angeles against the wind 45 minutes quicker than what was available at the time. It was reregistered as NAC and remained stored for several years. This was just one of dozens of Cuban hijackings during that time period. The manufacturer would build the fastest aircraft to ever take to the skies at the time, flying 25 to 35 miles per hour faster in cruise than the and DC Like most versions of the J79, the CJ and CJ were smoky, although secondary operator Spantax eventually had their engines refitted with low-smoke combustion chambers in the s.
