PS What's the third aircraft up from the bottom right facing "west" (if you regard North as the top of the page. ) It looks a bit like a BAC 111 but the tail is wrong. The Tristar further up looks like an old Saudia one.

Most will (probably) leave as coke cans, some may leave in parts and a few may actually fly out.
You’ll note the Tristars, 707s, 727s IL76s etc aren’t exactly cutting edge technology so usual commercial demand for them will be between zero and not much. Some may return to ‘niche’ markets or for nefarious purposes but most wouldn’t move again.

"California’s Mojave Air and Space Port keeps fleets of old Boeing, Airbus, and Lockheed aircrafts. The carcasses are picked apart for usable parts, and when there’s nothing of value left, the remains are melted for scrap metal."
"Once a jet has been stripped bare of usable parts, its metal frame is redeemed for scrap value. A 747 can fetch up to $55,000 for its scrap alone."

Most aerospace aluminium specifications call for around 10% of the charge for a melting furnace to be scrap, and most of this will be runaround scrap in the plant making the ingots/plate/extrusions. 2xxx alloys will have a Zn maximum of <0,2wt% so if you melt an aeroplane down you can't really use the resultant alloy for 2xxx ingot production. Most likely the scrap will be used for casting alloys where the specifications are significantly more relaxed.

I'm intrigued by the four instruments on the leading edge of the upper FE panel? Suspect they are either N1 or N2 gauges, maybe EPR that would be in the vsision scan of the FE when facing forward? Were these a BOAC mod, or was the airplane delivered this way as I have never seen that config before.
Terry McCassey: I replied earlier to this query. They were fuel temperature gauges. The Conway engined aircraft had manual fuel heaters and every time a change of fuel tank feed was done the heaters had to be "toggled" to the required temperaure as the tanks could have quite different fuel temperatures on a long flight.
I think this function must have been automatic on the JT3D engines as I have no recollection of needing to do this with them.

As I recall the JT3D engines, we used to apply fuel heat at a regular time (30 minutes?) for 1 minute when the #1M tank temp was below a given temp. Tank #1M was the only one with a temp sensor. We also used to apply 1 minute of fuel heat if the fuel icing light illuminated for any engine.
I apologise if I've got it all mixed up, I last flew B707 as FEO in 1977.

Yep Spooky, most of my colleagues used to do the same with the icing light cap.
If you had a Cpt who wanted to fiddle around with the thrust coz you weren't exactly at M.81, fuel heat was quite useful to make him cease fiddling. Turn it on, turn it off and thrust went all over the place.
