Following on from the loss of SS Braun, NS has admitted that contact has been lost with SS Corkscrew which is commanded by Tiger. However, NS said the Corkscrew was on a very long range secret mission beyond the range of NS communications and therefore the loss of contact was not unexpected.
Privately though NS are said to be concerned as the ship has been sent to investigate space in the direction of the Mutre Bee Organisation's territory. However, this means the ship has had to pass between 7 Sa Sao factions space, which explains the difficulty in communications.
