On the night of 21 December 1988, a Boeing 747 came apart in the dark and fell onto a small Scottish town. By the time the sun rose, the county of Dumfries and Galloway had become the largest crime scene in British history: 270 people dead, wreckage strewn across some 845 square miles of hillside and farmland, and a local police force of a few hundred officers standing in fields that now held the evidence of an international murder. The Bombing of Pan Am 103 begins in that field, and it stays close to the ground.

The six-part series, directed by Michael Keillor and written by Jonathan Lee and Gillian Roger Park, is a scripted reconstruction of the transatlantic investigation that followed the attack — Scotland’s smallest force working alongside the FBI and the CIA — and it arrives on Netflix as a global title after first airing on BBC One. It is not a film about the men who built the bomb. It is a drama about the people who had to trace it, and about the years of methodical work by which a fragment of circuit board no larger than a thumbnail was turned into a name.

That choice places the series inside a specific and increasingly confident British tradition: the catastrophe told through its procedure. Chernobyl found its subject in the machinery of denial; The Salisbury Poisonings in the machinery of public health; Mr Bates vs The Post Office in the machinery of institutional indifference. The Bombing of Pan Am 103 finds it in the machinery of forensic patience. The lineage matters, because it tells you what the series is trying to be — not a thriller organised around a ticking clock, but a study of attention as a form of moral labour.

Keillor directs against spectacle, and the discipline is the argument. The explosion itself is rendered once, in practical effects, and then withheld; the series declines to replay it for effect. Mogwai’s score sits low and grey beneath the fieldwork rather than swelling over it. The editing favours duration over momentum, letting scenes run to the length of the tasks they depict, because the real investigation took years and the drama wants that weight transferred to the viewer. A case of this size, the grammar insists, is not cracked in a courtroom epiphany. It is assembled from thousands of small, exhausting acts of looking.

There is a landscape argument running underneath all of this. Keillor and his cinematographers frame the Scottish hills the way the investigation had to read them — as a surface to be searched, quadrant by quadrant, in bad light and worse weather. The long takes are not decoration; they reproduce the tempo of a search that could not be hurried, and they keep returning to the horizontal sweep of the land rather than the vertical drama of the sky. In a genre that usually points its camera upward, at the falling plane and the fireball, this series keeps looking down, at the ground where the work happens. The direction reads the space, and the space is the case.

The performances are built to the same scale. Connor Swindells plays DS Ed McCusker, the Scottish officer whose jurisdiction abruptly stretches across the Atlantic and who carries the strain of a community investigating the thing that fell on it. Patrick J. Adams is Dick Marquise, running the American side of a task force that must coordinate agencies with different instincts and different secrets. Merritt Wever is Kathryn Turman, the State Department liaison whose responsibility is not the evidence but the families — the relatives who need someone to tell them the truth slowly. Around them, a bench of Scottish actors — Peter Mullan, Tony Curran, Kevin McKidd, Phyllis Logan — grounds the drama in the place the attack actually landed.

Keillor keeps these strands parallel and resists the temptation to braid them into a single hero’s throughline. That structural refusal is deliberate: a crime whose scale outruns any one jurisdiction cannot be held inside one frame, and the series would rather show the seams — the jurisdictional friction, the mistrust, the moments where police work and intelligence work pull in opposite directions — than smooth them into a myth of the lone detective. The result is a portrait of institutions under pressure, closer to the anxious realism of recent British drama than to the reassurances of the genre.

The Turman strand is where the series risks the most and gains the most. Merritt Wever plays a functionary whose function is grief: she has to sit with parents and partners and give them the truth in the only doses they can bear, while the evidence she cannot yet share accumulates elsewhere. The drama uses her to hold a line most terrorism stories cross without noticing — the line between the case as a puzzle and the case as 270 separate absences. Every procedural beat on the McCusker and Marquise sides is quietly weighed, in her scenes, against the cost of getting it wrong. It is the ethical ballast the genre so often lacks.

It is also a series that knows exactly where its own centre refuses to close. Only one man, Abdelbaset al-Megrahi, was ever convicted of the Lockerbie bombing, and his conviction has been contested almost since it was handed down. His release on compassionate grounds in 2009 and his death in 2012 left the case legally settled and publicly unresolved, and a renewed American prosecution — of a suspected bomb-maker extradited decades after the attack — has since reopened the question of who else bears responsibility. The Bombing of Pan Am 103 does not pretend to answer that question. It stays with the labour, and with the people for whom the labour was never the same thing as an answer.

This is the tension the series leaves deliberately open. The investigation succeeded, in the narrow sense that it produced a name and a trial; and it failed, in the larger sense that a courtroom closed the case without ever settling it. Two hundred and seventy people died, one conviction followed more than a decade later, and the families were left inside the gap between those two facts. Keillor ends there rather than sealing it, and the restraint is the most honest decision in the film. The camera stays at the height of the people doing the work, not the height of the falling plane.

There is a further reason the series feels newly charged. A drama first broadcast to a British audience is now released, all at once, to a worldwide one — a national reckoning turned into simultaneous global viewing. What Britain absorbed as its own history, the streaming audience is invited to reopen together, at the exact moment a real prosecution is trying to do the same in an American court. The distance between a local field and a global platform is, in a sense, the distance the whole series is about.

The Bombing of Pan Am 103 runs to six episodes. It was made as a BBC co-production by World Productions, first broadcast on BBC One in May 2025, with an original score by Mogwai, and it becomes available worldwide on Netflix on 30 July 2026.
