Similar Developments
In 1954, the McDonnell XV-1 was developed as a rotorcraft with tip jets to provide vertical take off capability. The aircraft also had wings and a propeller mounted on the rear of the fuselage between twin tailbooms with two small rotors mounted at the end for yaw control. The second prototype of XV-1 became the world's first rotorcraft to exceed 200 mph in level flight on 10 October 1956. No more were built and the XV-1 project was terminated in 1957.

Famous quotes containing the words similar and/or developments:
“We do not need to minimize the poverty of the ghetto or the suffering inflicted by whites on blacks in order to see that the increasingly dangerous and unpredictable conditions of middle- class life have given rise to similar strategies for survival. Indeed the attraction of black culture for disaffected whites suggests that black culture now speaks to a general condition.”
—Christopher Lasch (b. 1932)
“I don’t wanna live in a city where the only cultural advantage is that you can make a right turn on a red light.
Freedom from labor itself is not new; it once belonged among the most firmly established privileges of the few. In this instance, it seems as though scientific progress and technical developments had been only taken advantage of to achieve something about which all former ages dreamed but which none had been able to realize.”
—Hannah Arendt (1906–1975)
