Supplementary notes:

(1) Pair of US military communications satellites, destined for geostationary orbit.

(2) Possibly an electronic ferret.

(3) US domestic communications satellite operated by the Radio Corporation of America, the satellite was “lost” at the time of apogee motor firing as injection into geostationary orbit was due.

(4) Orbital data are at 1979 Dec 12.5, Dec 13.4 and Dec 15.3.
