All the Bell pictures have been so blurred or blacked out. Other pictures are out there, but they seem to think their tilt-prop solution is novel
enough to protect. Not really my area, so I couldn't even tell you what is so special about the unblurred pics.
Making good progress, I'd say and they are being cautious. Lots of people are watching this to declare tilt rotors are a bust. The V-22 haters are
waiting like vultures. Hence, caution.
