Where 737 fits
Why 737 is special
Over eleven thousand have been built since 1967. Fitting modern high-bypass engines to an airframe designed to sit low to the ground drove the changes behind the 737 MAX, which was grounded worldwide for twenty months after two fatal crashes.

Read as powers of two: 512 + 128 + 64 + 32 + 1 = 737.
In historical numeral systems
Egyptian
7 coils of rope, 3 hobbles, 7 strokes
7 × 100 + 3 × 10 + 7 × 1 = 737. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
1 corner wedge + 2 vertical wedges (sixties place), 1 corner wedge + 7 vertical wedges (units place)
12 × 60 + 17 = 737. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then lambda, then zeta, marked as a numeral
psi-lambda-zeta + keraia
psi + lambda + zeta written in descending order and added — the letters carry their values wherever they stand, so this is addition, not place value.
Hebrew numerals
tav, then shin, then lamed, then zayin
tav-shin-lamed-zayin
tav (400) + shin (300) + lamed (30) + zayin (7) = 737, written in descending order.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

The most-produced jet airliner and the first wide-body. The 737's low-slung airframe, designed in the 1960s, is what made fitting modern engines difficult enough to drive the MAX changes.
