Boeing 707-320B
Boeing Commercial Airplanes
About
The 707-320B put JT3D turbofans and an extended, re-profiled wing on the intercontinental airframe. Boeing tabulates it at two certified standards, 328,000 and 336,000 lb ramp; this row carries the higher of the two. A take-off weight of 335,000 lb is possible with wet thrust. 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.
