Data on around‐the‐world (RTW) propagation obtained at Ithaca, N.Y., between the years 1965 and 1968 are described and discussed using a ray optics approach. The role of the oblique ionospheric shells that are known to exist near the 75° dip of the northern geomagnetic field in producing RTW echoes is emphasized. The possibility of utilizing RTW waves for ionospheric sounding is pointed out.
