Size It Up Vehicles answer: September 18

The five Vehicles silhouettes for September 18, 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 15 ran from a Segway MAX G2 (1.21 m) to a Falcon Heavy (70 m). The widest gap was round 5, Segway MAX G2 against Hot Air Balloon, at 17×; the closest call was round 3, Spitfire Mk I against Jet Ski, only 2.8× apart — the kind of round that separates a 90 from a 60.

  1. ROUND 1

    Jason ROV vs Cat 320 Excavator (shipping pose)

    Cat 320 Excavator · reference · 9.53 m
    Jason ROV · true length · 3.4 m

    2.8× shorter than the Cat 320 Excavator

    Jason is about 3.4 m long. Its tether connects this compact underwater robot to a support ship far above.

  2. ROUND 2

    C-130J-30 Hercules vs Cessna 172

    Cessna 172 · reference · 8.3 m
    C-130J-30 Hercules · true length · 34.37 m

    4.1× longer than the Cessna 172

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

  3. ROUND 3

    Spitfire Mk I vs Jet Ski (three-seat runabout)

    Jet Ski · reference · 3.3 m
    Spitfire Mk I · true length · 9.1 m

    2.8× longer than the jet ski

    A Spitfire Mk I is about 9.1 m long. The propeller disc adds height to this side view, not length.

  4. ROUND 4

    Falcon Heavy vs Electron Rocket

    Electron Rocket · reference · 18 m
    Falcon Heavy · true height · 70 m

    3.9× taller than the Electron Rocket

    Falcon Heavy stands 70 m tall. The side boosters make it wider without making the central stack taller.

  5. ROUND 5

    Segway MAX G2 (unfolded) vs Hot Air Balloon (typical envelope)

    Hot Air Balloon · reference · 20 m
    Segway MAX G2 · true length · 1.21 m

    17× shorter than the hot air balloon

    The MAX G2 is 1.21 m long. Its handlebar stands higher than that, but this round measures horizontally.
