on p.56, 2nd paragraph under Specialties:
The Engineer skill description on p.64 & 65 lists:
"M-Drive, J-Drive, Life Support, and Power".
So, there are two issues:
1) The example should state "Life Support" instead of "Electronics"
2) There should be consistency between the names used in the example and the skill list. I prefer "Jump Drive" and "Manoeuvre Drive" over "J-Drive" and "M-Drive", but that is up for debate. Just be consistent, whatever you go with.
For example, a Traveller might have Engineer 0, allowing him to make Engineer skill checks without the unskilled penalty. He might then gain a level in Engineer, at which point he would need to choose a speciality.
For Engineer, this is a choice between Jump Drive, Manoeuvre Drive, Power Plant and Electronics.
