When an ufo is detected I find strange that the base spotting the ufo isn't in the pop up. Unless you can spot the red point on the map on the edges you need to center on ufo fist then intercept it. If the pop up message was UFO 54 was spotted by Base 1, you will know that base 1 interceptor should be your first choice.
Hyperwave decoder: a suggestion:when an UFO is spotted race should be indicated only if you have researched a living specimen of the race, mission is indicated if you have researched mission type and ufo type is indicated only if you have researched ufo type. This way these rather useless research topics should gain importance.
