The New Guess the Mission Chain Game

Hi, I thought it would be a good idea to start a new chain game in an all new format.
The way to start a question is simple. The first letter of the mission name is the question.
Eg 'B' would mean 'Big Smoke' therefore Big Smoke is the answer.
The person who gets the answer correct will be the person who is able to ask the new question.
I will check back here now and then to update the score.
1 correct answer = 5 points

Ok, I will ask the 1st question

I (clue: helicopters)
