In Koninklijke L. M. v. Superior Court (1951) 107 Cal.App.2d 495, the five decedents were either passengers or crew members of a private airplane owned by Superior Oil Company which crashed while taking off from an airfield in London. In the subsequent wrongful death actions filed in Los Angeles County it was alleged that KLM was negligent in performing certain maintenance functions on the crashed aircraft. KLM moved to quash service of summons, and, upon denial of such motion, it sought relief by petitioning for a prerogative writ. Relief was denied, and California jurisdiction was confirmed based on a showing that KLM maintained two offices in California, one for the solicitation of business and the other, a technical one, to facilitate its purchases in California of approximately $1 million worth of aircraft each year. KLM also maintained a checking account at a California bank to service its California payroll. All this added up to sufficient presence in the state to make reasonable the exercise of jurisdiction over KLM. As the court stated, "Since this is a transitory action, the court has jurisdiction hereof and since petitioner is doing business in the state . . . it is immaterial that the subject matter is wholly unrelated to any of the business conducted by the petitioner in this state."
