In my local group, we were under the impression that Second Chance was removed from play once it was used. Meaning it could not be retrieved from the discard pile. I was wondering if the designer's intent was to put "remove this card from play" instead of "discard this card from play"? Since the discard is an out of play state, it has been brought to my intention it can be targeted by things like Starship Graveyard. Logic tells me the intent was for this was for it to be gone from the game, thus the portion about "from play". If the intent was for it just to be discarded, that extra bit would not be necessary.
The same question could be asked of Thermal Detonator or Infantry Grenades.
