A summary is given of aspects of special relativity considered to be pertinent to engineering understanding of interstellar flight. In particular, the implications of the concept of proper velocity, the effective velocity for a passenger, are reviewed. Limitations on interstellar flight in terms of time, acceleration, energy, and power are evaluated. Certain potential avenues open to propulsion and energy-source technology to achieve acceptable interstellar travel within these limitations are cited. In particular, the capabilities of electron-beam propulsion and antimatter-annihilation energy production are examined.
