Diamond Twinstar
Probably one of the coolest experimental aircraft twin-engine aircraft is the Diamond DA 42 Twinstar. Since the aircraft is all-composite, it is light and fast. The slow airspeed characteristics are great and low stall speed range is certainly a plus. Although it looks like a twin trainer, yet a little racier it is not intended for training, however the price is quite attractive if you are comparing it to any new modern day high-performance single engine aircraft and you get the safety of two-engines. The new four-seater twin has retractable landing gear and will cruise at 18,000 feet on 11.

Laser Beam Guidance for Oshkosh Air Show
Each year at Oshkosh Wisconsin is the annual Experimental Aircraft Association, the largest event of its kind in the world. This system would be used when the aircraft in question cannot be contacted on VHF voice radio by ATC. Because general aviation aircraft often fly at relatively low altitudes, today's strongest lasers may pose a threat to the safety of the flight in all flight regimes. To do this is will use a laser beam pointed at the aircraft in a certain color. According to NORAD officials, the ground-based laser system uses safety-tested low-level beams of alternating green and red laser lights to alert pilots that they are flying without approval in designated airspace.
