Russians step up the 'probing' flights

Another claim that is rubbish. Of course we had heard of the E6

[TheGreenGoblin]

To use its Very Low Frequency radios, an E-6 has to fly in a continuous orbit at a high altitude, with its fuselage- and tail-mounted VLF radios trailing one- and five-mile-long wire antennas at a near-vertical attitude! The VLF signals can be received by Ohio-class nuclear ballistic-missile submarines hiding deep underwater, thousands of miles away. However, the VLF transmitters’ limited bandwidth means they can only send raw data at around thirty-five alphanumeric characters per second

Certainly would take a long time to transmit War and Peace, particularly when flying at a near vertical attitude

Shome mishtake shurely... the near vertical attitude I mean! I can do the maths on the long wave low frequency antenna and they have to be, long, some 2.5 to 5 miles long in fact! The antenna is meant to be deployed as close to the vertical as possible! So a shaped weight is used.

Ric, I looked up the word and indeed, that is what it was, a new word for me.

Each face had three apertures, one square, one circular and one triangular, I know not why.

The ELF story is a fascinating one.

I presume ELF can be detected by whales and elephants?
