I was watching Behind Enemy Lines, and one of my favourite scenes is the jet attempting to evade the missiles.
All this got me thinking about the Defiant from Deep Space Nine, and some research shows it doesn't have flares for defensive purposes. It's possible by this point in time technology would have made the use of flares obsolete. It's also possible that physics doesn't work that way in space.
Realistically, if you have 2 space craft, can one fire a missile and the other eject flares in an attempt to evade the missile as shown in the clip? If not, what would happen to the missile and flares?
