To you again - 411A -
I am just trying to scratch my old mind and memory about our dear 707 and 720s... facing these details, for now, years of so many questions, which are relevant or not here in the A.Net, and particularly in our Tech/Ops forum...
I remember, joining PanAm, initial 707 training, we had to study (listing them by size and weight) the 720-030Bs, the 707-121Bs, the 707-321s, the -321Bs, the 321Cs (some in pax configuration, some cargo) then some difference of odd airplanes that PanAm inherited from other sources, I can recall the few 331s originally meant for TWA.
Coming from the Air Force KC
-135 tankers, was already quite a bit of difference (I originally got a 707-720 rating on my pilot's license) to learn that there were differences with civilian machines.
Then, in hotel bars around airport, we the good guys who wore "white hats" met our buddies from AA
, from TW
, from NW
, from Continental or from Western, to realize they had more differences between "their 707s" and ours.
Even our check lists were sometimes different, our books were completely different. During a layoff from PanAm, I joined Saudia, to learn that they did all by the TW
bible, new differences, new options, new engines.
Just to mention the FAQ in the A.Net about the 707-720s...
- The HF
antenna "is that on the 720"...?" to mention that one...
- The 100 short body and long body (138B and 131Bs...) -
- The tall tails, the short tails, the tail fins (large, small, or... none) -
- The 320C with windows, without windows, with extra aft emergency exits -
- The "hump" on the engine for the TCs (how many, a favorite A.Net one) -
- The 720-025 ex EAL with 2 L and 2 RH
overwing exits -
Shall we mention to them, for pilots -
- Airplanes with air cycle air conditioning, others with freon -
- The parallel or series yaw dampers -
- The fire handles located on glareshield, newer airplanes, overhead panel -
- Planes with tiller steering on LH
side (Qantas) -
- Planes with hydraulic ground interconnect permitting gear retraction -
- The various antiskid systems, Mk.1 or Mk.2 -
- Variances in flight instruments and navigation systems -
And how many things did we forget...?
Oh, yes, the HF
antennas located on wing tips of the VC
Let us go back to the museum, one day maybe.
