Sounds familiar. We used a typewriter whenever available when receiving Morse and had special typewriters for the job. They had no shift function, just four rows of characters all caps and one row of numerals. They also had continuous paper feed with a big handle for 'form feed' function, I wish I could find one of those machines but they are scarce even on the Internet.

Most of our TTYs were American Teletype Corp, page printers, tape cutters, tape readers etc. I did a lot of software for ITA2.
Been in data comm since we formed the bits individually with a Morse key.

Nowerdays that could probably be done with an Arduino and an old cell phone!

True! Sensor technology needs a good base operating control system to connect to though. I bet you are a Rasberry Pi man too! ;)))

The basic theory goes back to the early 50's but the Snark proved that the gap between theory and practicality was to too wide, at that time anyway.

The Snark Missile
Many in the U.S. Military were surprised the Snark, due to its dubious guidance system, was ever operational. In flight tests many were lost. A missile launched from Cape Canaveral in 1956 that was supposed to fly to Puerto Rico and back flew so far off course that it was last seen on radar off the coast of Venezuela. The wayward Snark missile was found somewhere in northeastern Brazil in 1983. Many of those connected with the program commented in jest "that the Caribbean was full of 'Snark infested waters'."
Of course the Snark looked upwards, to the stars, not downwards to the ground, like the Tomahawk...

The Russians have continued to persist, always at least 10 years behind the curb in the last two decades... Techno-barbarians that they are...

I have one of these in the drawer but have not played with it yet.

Just the thing for guiding and control of a home-brewed pulse jet tank buster.

John, I am really keen to discuss this, but we are going to be moved or even banned from this thread.

Let's ask the Admin, for our own space.

I suggest the title of that new category should be James Clerk Maxwell Stuff...

You being a Kiwi, might, probably prefer, Rutherford... :-bd

No no no, you do not understand! I only put the tank buster comment in to make it relevant to this topic and therefore not to be shunted off to a dark corner!

Mind you, our own private club could be interesting but how could we keep ***** and #@$%$ out?

Frank Bell would have to be on the heroes board somewhere.

OK me just humble aircraft driver and have forgotten all these things. I am sitting here with my tea mug from BA Executive donkey's years old. It Says AFTN: EGLL BAWP. SITA: LHRPEBA. What was the difference between AFTN and SITA? Oh by the way it also says Passenger reporting point: Desk 73 Terminal 1 if that is any help to anyone.

The AFTN is a child of ICAO and (usually?) established and operated by state ATS organizations. SITA is a company founded by airlines.

Thanks John, I vaguely remember that now.

In the 1960s the RAF used teleprinter and Morse to provide circuits between RAF stations around the world. Most used purely military procedures (ACP124 for Morse circuits, ACP127 for torn tape systems, etc) but the RAFAN (RAF Aeronautical Network) used ICAO procedures and ICAO location indicators from ICAO Doc 7910
