USA-81
1992-023A
The third Titan 23G test payload was launched in Apr 1992. It was discovered shortly after launch by R. Kracht in an orbit similar to that of USA 32 but in an orbital plane displaced by 90 degrees. This satellite was registered with the UN, with a low parking orbit of 145 x 175 km given. This may be the orbit of the Titan rocket just prior to reentry, rather than the actual parking orbit of the payload.

Pegsat
1990-028A
Pegsat was a test satellite for the first Pegasus launch and it remained attached to the Pegasus Orion 38 third stage motor. Developed by NASA-Goddard and built in-house, it carried Barium release canisters left over from the CRRES program as a bonus scientific experiment. The NB52 008 carrier aircraft took off from RW04/22 at Edwards AFB at 1803 on 1990 Apr 5 and flew out over the Point Arguello Warning Area 80 km W of Vandenberg AFB. At 1910:17 the B-52 dropped the Pegasus at an altitude of 13 km. First stage ignition was at 1910:22, burnout at 1911:38 at an altitude of 70 km. Stage 2 ignited at 1911:47 at 76 km, and burnt out at 1912:59 at 198 km. The second and third stages remained attached for a coast period, then at 1918:39 the second stage separated and stage 3 ignited for a 66 s burn at 537 km altitude. Earth orbit insertion was at 1919:45 into a 508 x 687 km x 94.2 deg orbit. The first barium canister was released on 1990 Apr 15; the second was probably released on 1990 Apr 17.

Zond 4
1968-013A
The L-1 No. 6 spacecraft was given the code-name Zond-4 after launch. The earlier Zond space probes were planetary probes in the MV series and entirely unrelated to the L-1 lunar program.
In an interview with Bert Vis, Vitaliy Sevastyanov reported that he and Popovich were participating in a simulated L-1 mission at Yevpatoria during the flight; their communications from the L-1 simulator were routed through Zond-4 in deep space and then back to TsUP. He said that the spacecraft reentered on Mar 9 over the Atlantic in the Gulf of Guinea, but was destroyed at an altitude of 15 km by ground command because no recovery fleet was available at that time. Another report claimed that attitude control failed on reentry and still other rumours suggested that it landed accidentally in China, but the Sevastyanov report has now been confirmed.
The Energiya history states that an orientation system problem led to a ballistic reentry and use of the auto destruct above the Gulf of Guinea. The intent was to make a 46 km pass and skip out to 145 km for final reentry,but the skip did not work and the auto destruct fired at 15 km altitude.
The reentry time implies an apogee of about 294000 km and a TLI velocity of 10.84 km/s.
