No warning, no heads up. The Embraer E195-E2 testbed aircraft came up to MCW on a windy day and did some pattern work, then landed and got some fuel. It's such a heavy aircraft that it had to be parked on the airline ramp as the FBO ramp wasn't rated for its weight. The airframe was outfitted with test equipment, and the Brazilian test crew was happy to show their plane. off. They gave us a show on the way out with a maximum performance takeoff. Definitely the largest aircraft MCW has seen in a long time.
