Kirk's Personal Log (The Immunity Syndrome)

KIRK: Captain's personal log, stardate 4309.2. We have established that the thing which destroyed the USS Intrepid and the Gamma Seven=A system is an incredibly huge but simple cellular being whose energies are totally destructive to all known life. Both Mister Spock and Doctor McCoy have volunteered to go in a specially equipped shuttlecraft to penetrate the cell, find a way to destroy it, and free the ship. Doctor McCoy has the medical-biological knowledge. Mister Spock is better suited physically and emotionally to stand the stress. Both are right, both are capable, and which of my friends do I condemn to death?
