Size It Up Vehicles answer: September 21

The five Vehicles silhouettes for September 21, with the true sizes. If you have not played yet, this page is a spoiler — play these five first, then come back to argue with the numbers.

Day 18 ran from a skateboard (80 cm) to the USS Missouri (270.4 m). The widest gap was round 3, Airbus A320neo against USS Missouri, at 7.2×; the closest call was round 4, Semi-Trailer Truck against Electron Rocket, only 1.1× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    London Black Cab (TX4) vs Skateboard

    Skateboard · reference · 80 cm
    London Black Cab · true length · 4.58 m

    5.7× longer than the skateboard

    The TX4 London black cab is 4.58 m long. It was made as a purpose-built hackney carriage from 2007 to 2017.

  2. ROUND 2

    Flying Scotsman (engine + tender) vs B-52H Stratofortress

    B-52H Stratofortress · reference · 48.5 m
    Flying Scotsman · true length · 21.4 m

    2.3× shorter than the B-52H Stratofortress

    Flying Scotsman is 21.396 m over the buffers with its tender. Passenger carriages are not included.

  3. ROUND 3

    Airbus A320neo vs USS Missouri

    USS Missouri · reference · 270.4 m
    Airbus A320neo · true length · 37.57 m

  4. ROUND 4

    Semi-Trailer Truck (tractor + 40 ft trailer) vs Electron Rocket

    Electron Rocket · reference · 18 m
    Semi-Trailer Truck · true length · 16.5 m

    1.1× shorter than the Electron Rocket

    A tractor with a 40 ft trailer runs to 16.5 m — the length most road-train limits are written around.

  5. ROUND 5

    C-130J-30 Hercules vs Falcon 9

    Falcon 9 · reference · 70 m
    C-130J-30 Hercules · true length · 34.37 m

    2.0× shorter than the Falcon 9

    The stretched C-130J-30 measures 34.37 m. The extra fuselage section makes the exact Hercules variant matter.
