The tornado was a euro colaboration and that was a huge succes (not to mention a beauty of an aircraft.)
The Tornado is certainly a nice looking aircraft. I'm not convinced it was/is a huge success. It was originally intended to be a multi-role combat aircraft (MRCA). This "one size fits all" concept was never likely to be practical. In the event, the first production models were fighter-bombers. Several different versions were developed to fulfil various roles for different air forces. It took 12 years to develop although it was delivered on time & within budget. Meanwhile, the best low-level aircraft the RAF possessed was the Buccaneer. It proved its value in the Gulf War & carried on while problems with the maritime attack Tornado were ironed out. This wonderful old bird, originally rejected by the RAF, was finally retired in March 1994, 36 years after its first flight.
