What happen on the ship that day when Keenser brought his alcohol on the enterprise.
When it had started in the engineering department, When the engineers disided to celebrate. The rest had been a blur. But here are the facts
1) the fire had nothing to do with the alcohol, infact the alcohol save an ensign and Lieutenant lifes.
The two scientist, Ensign Millbrook and Lieutenant Tahan were looking at samples of an unknown plant from an new plant. Unfortunately H2O cause the plant to burn and catch on fire. Both of their hands and shirts caught on fire as well. Ensign Novak from engineering threw the alcohol on them on the fire stopped, both the males were okay just very bad burn bluster on their hands.
2) the tribble investigation was a lot of people fault.
The main was no one checked if the tribble was neutered and someone who has not come forward. Open the cage. And in the next few minutes the enterprise was shut down due to millions of tribbles on the ship.
3) It is not Keenser fault everyone was in light weight.
Most of the crew had past out, but the Captain was running around the ship in his birthday suit which almost give poor Dr McCoy a heart attack. Which is why we are not allowed to talk about it.
No one really remembers, but the Captain doesn't want anyone to mention it. It not like 40% of the crew has already seen him naked. Another thing no one is allowed to talk about.
