    …Brief article discussing the 2005 Sikorsky acquisition of Keystone, and development of the helicopter facilities near Coatesville’s airport.
  • 4-27-1989Propelling A Takeoff Of Growth
    …Archived article from the Philadelphia Inquirer, with many details of the history of this airport. In 1989, there were big plans to extend the runway from 5,400′ to 6,400′. The article also notes that 23 private business jets were based there (apparently an early example of locating corporate jets at ‘garage airports’, for call up when needed at Teterboro, White Plains and other major business airports). The article also discusses many rounds of FAA funding, for both Coatesville and nearby Brandywine (where MBB had set up a competing helicopter business).
