Aircraft charter and management firm Talon Air added four new Hawker 4000s to its Part 135 certificate this week. The super-midsize jets are based at Talon’s new 100,000-sq-ft hangar and office complex at New York’s Republic Airport in Farmingdale, Long Island. With nine Hawker 4000s on its charter certificate–nearly one-fifth of the in-service fleet of this type–Talon remains the largest owner and operator of these twinjets in the world.
