Hi BEags and Wolf1965.
The following is an extract from a letter to Andrew Hunter MP from Adam Ingram. It is dated 13 June 2001.
Mr (Brian's friend) particularly mentioned an unconfirned report that one of the passengers may have been using a "TETRA telephone". Terrestrial Trucked Radio (TETRA) is a standard for digital radio that started development in 1990 to meet the requirements of professional users including the emergency services.
Fielded TETRA systems did not begin to appear until 1997. Given the time-scale it is very unlikely that a telephone using the TETRA standard could have been on board Chinook ZD576. Certainly there was no evidence of such a telephone found in the wreckage.
However, I'm just about to send another letter to the MoD, so will include one or two more questions on this particular issue. As always, I'll let you know what comes back.
My regards, as always.
Brian
