Size It Up answer: October 15
The five Mixed silhouettes for October 15, 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 42 ran from an AAA battery (4.45 cm) to Ben Nevis (1.345 km). The widest gap was round 3, Giraffe against Ariane 5 ECA, at 9.6×; the closest call was round 2, Tram against Delta II Rocket, only 1.2× apart — the kind of round that separates a 90 from a 60.
