Mile High Club/Trivia

• Mile High Club is slang for engaging in sexual activity aboard an aircraft.
• The terrorist holding the hostage can be shot by other members of the squad if the hostage escapes. This happens if the player shoots the terrorist's gun or shoots the terrorist's leg.
• According to the "dev. only" missions when enabling the developer cheat via the console in the PC version, "Mile High Club" was the first level to be completed, with a completion date of April 2007.
• In the briefcase containing the bomb, there is a small picture of a comical-style bomb grinning, and the word, "Booooooom" written alongside it.
• Some unused audio files shed some light on the mission's purpose:
  • airplane_gaz_1_1_R has Gaz saying "Remember, the objective is to capture Kriegler, I repeat, capture Kriegler, alive. He's no good to us dead."
    
     
  • airplane_gaz_7_2_R has Gaz saying "Watch your fire up here, we need Kriegler alive."
    
     
  • airplane_gaz_9_1_R has Gaz saying "Nice one, Soap."
    
     
  • airplane_gaz_9_5_R has Gaz saying "We're going for a little free fall Kriegler! On your feet!"
    
  • The sound files also indicate that the hostage the player rescues is Russian.

• At the beginning of the mission, two members of the player's squad have a conversation with each other, saying "We're going deep, and we're going hard." to which the second replies "Surely you can't be serious?" and the first says "I'm serious... and don't call me Shirley." This is a reference to the parody-comedy film Airplane!.
• When finished with the mission, a picture is shown of Vasquez, Gaz, Price and Griggs in a line. Some writing to the side of them says "Semper Fi". This is the motto of the United States Marine Corps, short for "Semper Fidelis" which means "Always Faithful" in Latin.
  • The words written on the picture at the end of the level is a reference to the movie Full Metal Jacket.
• With the use of 'Ragtime Warfare' or the Wii version, a TF141 member says "Drop the weapon! Down on the floor, now!" during the slow-mo part.
• It is possible to switch to the primary weapon when shooting the final enemy by switching to the USP .45 before reaching the final door.
• The music heard throughout the level is a blend of all themes played during the campaign and is titled "Don't Call Me Shirley."
• According to Soap's Journal, this level takes place after the events of Call of Duty 4, is conducted by Task Force 141 and takes place at 9:37 in the morning.
• Although a Task Force 141 member actually says "Shit, someone armed the bomb" the subtitles say "Shite, someone's armed the bomb" which is pronounced differently.
• The dead civilians on the plane are of extremely low detail.
• After rescuing the hostage, the TF141 member, who is standing down the stairs, loses the plot armor and can be killed without any penalty.
