Nick and Steve,
The individuals have since left and returned to the army but they were definately talking about the 'Hawk. Would seem perhaps to be one of those urban myths that develops some where and has a life of its own although they did talk of demonstrating it to students. Will try and contact one of them and see if they will post.

Nick,
An after thought. The guys mentioned read the list so your emphatic reply should give them the message.
