Size It Up Vehicles answer: October 24
The five Vehicles silhouettes for October 24, 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 51 ran from a Spitfire Mk I (9.1 m) to a nuclear submarine (170 m). The widest gap was round 2, Cat 797F Mining Truck against Delta II Rocket, at 2.6×; the closest call was round 5, Spitfire Mk I against Gondola, only 1.2× apart — the kind of round that separates a 90 from a 60.
