Blue Thunder is a 1983 action film about a police helicopter pilot who discovers a Government Conspiracy to use an experimental Black Helicopter for urban riot control. It earned an Academy Award nomination for Best Film Editing and kicked off a subgenre of Cool Helicopter shows including a short-lived 1984 TV series of the same name and the enormously more popularAirwolf.Frank Murphy (Roy Scheider) is a Vietnam War veteran who flies helicopters for the Metropolitan Police Astro Division. In his time off, he deals with a failed relationship and his fears of going crazy, based on flashbacks he keeps getting to a traumatic 'Nam mission. In the course of training a new observer, rookie Richard Lymangood, he witnesses what appears to be the planned murder of a city councilwoman, but when he tries to report his suspicions, he's grounded due to earlier "extracurricular" activities.Murphy tries to follow up on the killing on his own time, finding a scrap of paper that calls attention to something called the "THOR Project". Before his investigation can bear fruit, however, he's called up and his suspension is lifted so that he can participate in field testing of a new helicopter. Code-named "Blue Thunder", it's a heavily armed and armored machine with advanced sensors and stealth technology designed for urban riot control. He also meets his nemesis, Colonel Cochrane, a gung ho military test pilot who knows Murphy from Vietnam, and not in a friendly way.During their first flight in Blue Thunder, Murphy and Lymangood decide to experiment with its stealth and sensor capabilities, while at the same time using the onboard computer to investigate THOR. They end up uncovering a conspiracy to incite unrest in the city's ghettos in order to showcase the new helicopter. When the bad guys realize they've been found out, all bets are off. The two must run for their lives with the evidence, and Murphy is forced to steal Blue Thunder and fight a high-stakes aerial battle over the city.
This movie contains examples of the following tropes:
Achilles' Heel: In the climactic battle, Blue Thunder's targeting system is knocked out by a lucky shot.
Black Helicopter: Blue Thunder is either black or very dark blue, but it fits the principle of the trope well enough, being designed for stealth.
Chekhov's Gun: Murphy's flashbacks, to a helicopter flight where a Vietnamese soldier is thrown to his death, finally reveal at the end that Cochrane is the one who did it. Also, the remote erase functionality for Blue Thunder's recording system, fortunately subverted in that it fails... by mere seconds.
"This ship is equipped with a forward-mounted, twenty-millimeter electric cannon. Its six barrels are capable of firing four thousand rounds of ammunition per minute. And that, gentlemen, is one hell of a shit-storm in anybody's language!"
Every Car Is a Pinto: Remarkably averted, to the point where things that you'd think would explode pretty easily — like helicopters — don't, even when shot out of the sky by Blue Thunder's rotary cannon.
Fake Static: "Cannot read you, Special Base. Still garbled." Murphy is later called out on this by Captain Braddock.
"Who are you fooling with that phony radio bullshit? Jesus Christ, Frank, that went out three days after Marconi invented the fucking thing!"
Gunship Rescue: When Murphy's girlfriend is being pursued by the police, he rescues her with Blue Thunder.
Heroic BSOD: Based on his Vietnam flashbacks and the fact that he constantly tests himself for "sanity", it seems as if Murphy is teetering on the edge of one of these for the entire film. note See the Trivia page for more on this.
Hot Pursuit: Murphy's girlfriend attempts to outrun the cops while carrying the tape with the evidence to uncover the conspiracy. Murphy has to rescue her with Blue Thunder.
Immune to Bullets: Blue Thunder itself, at least to normal ammunition, although it has a few weak spots, particularly when military-issue armor-piercing rounds are involved.
Minor Crime Reveals Major Plot: An apparent rape/mugging turns out to be a contracted hit which is in turn part of a larger conspiracy to incite urban riots.
More Dakka: The reason for Blue Thunder's existence.
Nice Job Fixing It, Villain: The bad guys arrange for someone in the media lobby to steal the tape; all he does is free the tape from its container in the struggle, just when his superiors have chanced on the right erase code.
No Endor Holocaust: The question of whether engaging a helicopter with Air Force interceptors over the city is necessarily a good idea is at least brought up, if glossed over. However, the news anchor narrating the ending seems to blatantly ignore any mass casualties from what transpires.
Power Perversion Potential: A variant — the Astro Division has a penchant for peeking in windows, and Murphy taking Lymangood to visit the "girl in Encino" (who happens to be quite fond of nude yoga and has a very large picture window) is what gets him grounded the first time.
Repeat Cut: Used twice, first in the climactic helicopter duel with Cochrane, and then at the end when Blue Thunder is destroyed by a train.
Stating the Simple Solution: After spending a lot of effort chasing down the tape with the evidence, one of the villains asks why they don't just remotely erase it, since it's previously established that they were designed with this functionality. The other villain replies that they don't know the code for the specific tape, to which he is told to just "erase them all", as if it should have been obvious.
Tagalong Kid: Lymangood, though he's not really all that annoying.
Technology Marches On: While the military hardware is still exotic, the informational systems (recording, wireless database access, etc.) look their age in an era of gigabyte flash drives, satellite wireless Internet, and ADS-B receivers.
Thou Shalt Not Kill/Bullets Do Not Work That Way: Murphy seems to go out of his way to avoid intentionally killing anybody while flying Blue Thunder around the city. All the killing in the movie, except for the very last battle with Cochrane, is done by the bad guys, nameless cops, or misguided military personnel (seriously, how do you justify firing heat-seeking missiles around in a goddamn city?).
Unflinching Walk: Accidentally subverted. Murphy flinches when the helicopter blows up behind him. (Director John Badham says he "didn't think [Roy Scheider] expected the explosion to be as loud and as big as it was.") At that point, Murphy was supposed to be exhausted, not to mention wounded, so "unflinching" may not have been the intent to begin with.
Wronski Feint: Used by Murphy to dodge heat-seeking missiles, with sunlight reflected from a highrise in one case, and the heat of a bakery's chimney in another.
