Ok, this is not strictly on-topic, but I bought an old American Airlines route map published sometime between 1970-72. Under passenger information, it asks that you refrain from using "portable radios, telephones or televisions" in flight due to possible interference with navigation systems.

Other than senior government officials, and maybe some celebrities/CEOs -- Who was using "portable phones" almost 35 years ago, much less on a commercial airliner ??

Probably just CEO's and gov't officials. A very very rare occurance. My wife who was a SAS stew from early 1969- 1983 never saw anyone with a portable(if you can call it that compare to today's standards) phone.

Heck, those things even existed back then?


As a question -- just what do portable phones do to aircraft navigation and how was this proven?

Interferce I think. But I don't know if it's been proven. Now Ericsson and Siemens are making equipment to put in the planes so they can use the phone without any interference with low frequency antennas that don't bother the plane.... but the passengers instead!

It's not about AIRBUS. it's not about BOEING. It's all about the beauty of FLYING.

Yes, the "shoephone" of Maxwell Smart... from the TV series "Get Smart".

Joe Patroni had a car phone in 1970, not sure how portable it was. He was, of course, a very important man.

There was a 2inch portable television introduced by Sinclair (of calculator, computer and C5 electric vehicle fame) in the early 1970's.

They were very expensive, I seem to recall c£200 - but I never saw one on an aircraft.

There were no "portable telephones" in '70-'72, at least in the sense we know them today. (wireless telephone)

What did exist at that time however were portable transceivers (contraction of transmitter/receiver), the older version of the walkie-talkie, a two-way AM radio.
The period saw also the transition from "all tube" (vacuum tube or valves) to hybrids (tubes + transistors).

Some (purely radio) networks had the ability to "patch" the radio to the (conventional - wired) telephone network, through a device called "phone patch" or "phone interconnect". It was still two-way, one talks / one listens.

The first such (trans)portable radios were often called "lunchboxes".  old

A mate who installed GSM networks once told me it was a "behind closed doors" deal between the phone companies and the airlines as it screwed up the billing and you ended up getting free calls. Obviously the phone company wouldn't be too keen on this!

Dunno if he was talking rubbish though, but a good theory all the same!!

Cell phones have existed since the late 1960s. I remember seeing an article in Popular Science where they tested one in NYC in the early 1970s. There were only two or three cells in existence in NYC at the time and the phone's batteries way a lot. One picture in the article showed the writer sitting in a rubber raft out in the Hudson, speaking on the phone, to show how portable they were.

The first test of what can be described as a wireless telephone (full duplex with direct conncetion to the public network) was made in 1974. (Motorola Dynatac)

I thought SAS conducted a test a few years ago to see wether cell phones disturbed instruments or not. Appearantly they found no problems using phones inflight.
