Airbus (AIR.PA) Chief Executive Tom Enders urged European governments not to place overly onerous political requirements on a joint project to develop drones, adding that the aerospace group could drop out if such conditions were not met. There should be one lead nation and one lead company on individual military projects, with suppliers chosen on merit, Enders told the Financial Times in an interview. “Pooling our requirements should be done intelligently and not in a highly politicized, nationally fragmented way,” said Enders, adding that he supported European co-operation.
