Is an invisible plane possible?

Can an aircraft be to be invisible? Not to radar but to visible light. The eye so to speak.

Yes says VeraTech, a high tech company based in Minnesota. Research is continuing on the Phantom Sentinel, an experimental aircraft that is expected to be Y-shaped, consisting of a single long wing attached to two short aerodynamic extensions which each end in a propeller. Combine that will an overall blue color and as many clear parts as possible and one additional feature…The drone aircraft will spin like the rotor on a helicopter with the net effect being something very similar to what happens to an aircraft propeller or the rotor of a helicopter. When something spins at a high rate, persistence of vision in the human eye renders the object virtually invisible.
