Do you need alien detection to find an alien base?

[chris.staddon]

I've read everything there is on alien bases appearing and know how I SHOULD be able to find one... following a supply ship... but I've yet to find one despite weeks of trying. The thought's occurred to me... do I have to be tracking a UFO with one of the new craft with alien detection as opposed to a Saracen or Stiletto (which use radar)? None of the forums say so but given I'v found zilch with the traditional craft... ?

Watch were it disappears at, then loiter there for a long time.  Send two or three craft in the area and have them just park, eventually it should show up.
