Boeing 707

The Boeing 707 was the aeroplane that made jet travel ordinary, and the ancestor of every Boeing airliner that followed — the 720 and the 727 both reuse its fuselage cross-section. It grew out of the Model 367-80 prototype into four series: the domestic -100 and -200, and the intercontinental -300 and -400, which have a longer body, a greater wingspan and higher gross weights. The -320C was built both as a convertible passenger/cargo aeroplane and as a pure freighter. The cruise speed, cruise Mach, range, ceiling, climb rate and take-off distance are EUROCONTROL's figures for the B703 type code rather than a certificate's: a type certificate states limits and weights, not cruise performance, and the source does not distinguish sub-variants. Cabin width and height are Boeing's own, from Boeing D6-58322, 707 Airplane Characteristics for Airport Planning, section 2.5, page 19: interior trim to trim 139.3 in (354 cm), 86.3 in (219.2 cm) floor to ceiling.
