      Apparent phase velocities of zonal structure, estimated from Mars Global Surveyor (MGS) electron density profiles, are used to identify and characterize SE1, the semidiurnal eastward-propagating tide with zonal wave number ...

    • The choice of V/STOL transportation for the Northeast Corridor 

      Swan, William M. (Cambridge, Mass. : Massachusetts Institute of Technology, Flight Transportation Laboratory, [1972], 1972)
      Aircraft type, aircraft size, number of terminals, and degree of nonstop routing for a V/STOL transportation system in the Northeast Corridor are chosen by exploring a wide range of combinations. Helicopter and STOL aircraft ...
