I originally asked about Mission 51-L, not STS-29. DOI was not part of
the plan for Mission 51-L, and I was well aware of that.

The OMS-I thrusting maneuver after main engine cutoff plus
approximately two minutes is eliminated in this direct insertion
ascent profile. The OMS-I thrusting maneuver is replaced by a 5-foot-
per-second reaction control system maneuver to facilitate the main
propulsion system propellant dump.
Because of the direct-insertion ascent profile, the external tank's
impact area will be in the Pacific Ocean south of Hawaii."

Quote: TDRS-1, TDRS-3, and TDRS-4 were all released from orbiters that had
insertion orbits in the neighborhood of 175 nm. (I'm not sure if all
of those were elliptical.)
NASA says a summary timeline was not available when the STS-6
Press Kit went out to reporters. From the NASA Archives we find:
<http://tinyurl.com/4m5k5o>
"Orbit Altitude: 184 nautical miles"
That altitude seems too high. Other references give lower altitudes
(some much lower).
Also, I'm a bit surprised that nobody here has mentioned STS-6 having
an insertion orbit that was a good deal less than 175 nm.
