707-138B
The 707-138B versus the -320B or C could not do the same missions.
The -320B/C ADV had more powerful engines and a higher fuel capacity (23800 v 17300 US gallons), and of course a 151000 kgs MTOW v 129000 kgs on the smaller 707.
The -138B had the same MTOW as a -120B, but was 10' shorter and thus had a lighter OEW.
Laker and BWIA who flew the -138B to the Caribbean from LGW both stopped usually at the Azores, or Gander/Bangor.
Laker used the smaller 707 to assist the Skytrain start up and could make JFK.
Laker carried 154/158 pax.
Qantas longest -138B sectors were SYD-SIN HNL-NAN SFO-HNL YVR-HNL JFK-SFO LHR-JFK LHR-BDA
From late 1964 saw their new Fiesta Route.
A QF Boeing 707 ‘V-jet’ would took off weekly from Sydney en route to London, via the opposite direction to the original Kangaroo Route.
It would have to stop several times for fuel, and possibly the route planners tried to make it as scenic as possible, with stops including Fiji, Tahiti, Acapulco, Mexico City, The Bahamas and Bermuda. The first service was aboard VH-EBM, the very aircraft that John Travolta would later own ,and the last -138B to be built for QF in 1964.
All up, the flight took 45 hours – 27 of them in the air.
For some reason at PPT was a day long stop arriving at 0835 from NAN, then departed at 2300 to ACA, but not on the way back.
The longest leg was across the Pacific from Tahiti to Acapulco, and the shortest leg was to Acapulco from Mexico’s capital, just an hour’s flight away.
However, this short hop served a very important technical purpose. Mexico City was too high above sea level for the Boeing to take off with full tanks, so the aircraft would fill up in Acapulco for the long flight ahead to Tahiti.
PER-MRU was not a -138B route but a newer -338C was used from 1966.
QF's -138B's had a usual config of 20F and 84Y, or 20F/78Y, or 28F/66Y all with a F lounge.
F had 42'' and Y had at least a 34'' pitch.
(There was until 1965, 20F/72Y)
There was also a 120Y.
