The technical analysis regarding the principle of the explosion scenes in Taken 2 and their relation to the Notre-Dame Cathedral fire of April 15, 2019, is translated below:

  1. Principle of the Taken 2 Rooftop and Chimney Scene: Acoustic Triangulation
    The method used by the character (Bryan Mills) to determine the location where he is held captive is based on the principles of Time Difference of Arrival (TDoA) / Acoustic Positioning:
  • Speed of Sound: Sound travels through air at approximately 340 \text{ m/s} (or \approx 1 \text{ km} / 3 \text{ s}).
  • Distance Measurement (d = v \cdot t): The character hears the sound of the detonation instantly via mobile phone (transmitted as an electromagnetic signal at the speed of light), and then counts the elapsed time (\Delta t) until the physical acoustic wave reaches the walls of the room.
  • Radius Determination: Multiplying the measured time by the speed of sound establishes a circular distance radius centered on the detonation point.
  • Triangulation: Plotting the intersecting radii of at least 2–3 grenades detonated on different chimneys/rooftops yields the exact coordinate fix of the target building.
  1. Analysis of Potential Connection with the Notre-Dame Cathedral Fire
    There is no physical, forensic, or operational correlation or commonality between the film Taken 2 and the Notre-Dame Cathedral fire of April 15, 2019. Parameter Taken 2 Film Scene (2012) Notre-Dame Fire (2019) Location Istanbul / Grand Bazaar – Caravanserais Area Paris / Île de la Cité Date Filming: Late 2011 (Release: 2012) Incident Date: April 15, 2019 Structural Material Stone, brick masonry, and clay tile roof 13th-century oak timber framework (“La Forêt”) and lead roofing Nature of Event Controlled pyrotechnic squibs (film set special effects) Uncontrolled structural fire (electrical fault / restoration area negligence) Forensic Report Outcome Cinematic production Paris Prosecutor’s Office & Fire Brigade: Electrical malfunction / discarded cigarette butt The pyrotechnic effects, external grenade tosses, and acoustic tracking scenarios depicted in the film are strictly fictional production setups; the Notre-Dame incident was an accidental timber roof fire caused by electrical and maintenance failures within the restoration scaffolding.
