KIRKUS REVIEW

In the familiar Bergaust format, the first full-scale, self-contained scrutiny of the convertiplane, ""an aircraft which can hover like a rotary-wing vehicle and climb and descend like one--or. . . a helicopter which is built to fly with the speed, economy and ease of a conventional airplane."" Technical and timely.
