interesting question. In the late-90's, Bell Helicopter tried to generate interest in a commercial passenger version of its V-22 tilt-rotor. Of course at that time its dismal safety record alone was enough to kill the program. But the complexity (too many moving parts) made it a maintenance nightmare, and operating... More

They would be prohibitively expensive and not very safe either. Besides, with the current state of engine technology, only relatively smaller aircraft could be made. And once the aircraft was airborne and flying normally, the extra thrust would be useless... More
