The third flight of TM-5 saw the return of visiting crew EP-3-2 to Earth. 30 seconds before deorbit, an IR horizon sensor alarm cancelled the burn. A 7s burn a few minutes later didn't work right and was aborted. After several more tries, the orbit was somewhat changed but still no deorbit. Automatic separation of the service module was cancelled only a minute before it would have occurred. Finally a day later a successful deorbit burn was made.
