In the mid 80s, this finally changed with the one Traveller adventure series which I thought was la creme de la creme: FASA's The Sky Raiders trilogy.
So if you picked up the Classic Traveller Books 1-3, do yourself a favor and set your sights on finding a copy of the Sky Raiders Trilogy. Throw a little Indiana Jones into your classic Traveller and you have instant awesomeness.
The books are not spectacular in the production values department (though pretty good given the standards of the era) - but the proof is in the playing. The full trilogy is Legend of the Sky Raiders, Trail of the Sky Raiders and Fate of the Sky Raiders - all written by the Keith brothers. Say "yes" to that campaign in a heartbeat.
Hands down the best classic Traveller campaign - ever.
