Where 767 fits
Why 767 is special
Extended-range rules were written around its reliability record, allowing twins to fly routes previously restricted to three- and four-engined aircraft. Every twin-engine ocean crossing today rests on precedent it established.

In historical numeral systems
Egyptian
7 coils of rope, 6 hobbles, 7 strokes
7 × 100 + 6 × 10 + 7 × 1 = 767. 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), 4 corner wedges + 7 vertical wedges (units place)
12 × 60 + 47 = 767. Places are separated by a space on the tablet, with the higher place written first.
Greek (Ionic)
psi, then xi, then zeta, marked as a numeral
psi-xi-zeta + keraia
psi + xi + 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 samekh, then zayin
tav-shin-samekh-zayin
tav (400) + shin (300) + samekh (60) + zayin (7) = 767, 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.

Related numbers & connections
Boeing developed the 757 and 767 together with a common cockpit, so pilots could fly both on one rating. One is a narrowbody and the other a widebody, which made the shared rating unusually valuable.

why?
Strength 0.50, confidence "high".
Technology & computing
Rules requiring three or four engines over oceans were relaxed on the strength of the 767's engine reliability. That precedent is why almost every transoceanic flight today is on a twin, which is a regulatory change as much as a technical one.
