UFO base attack detection distance.

Hi Al.

Just found OpenXcom and I love it as this is what Xcom should have been all along!

But something odd happened as I'm only in early March and I got hit with a base defense mission, yet no UFO's came closer than a few hundred km except for one very small one that did fly right over it but it was going 2200 (full speed.)  So my question is how close does a UFO have to get to detect an X-Com base as what I remember is obviously wrong, or maybe it was changed?

Also my fear now is that since the aliens know where I am I'll get swamped with so many base defense missions the game starts to become to much of a grind as that happened with one of my games back in the day, and I'm a **LONG** way from being able to shoot down alien BB's so I'm wondering if I should just start over.  Thanks.

268 nautical miles, or 496 kilometers

After the first base defense mission, they will forget the location of your base.

Thanks for the reply.

And wow, basically 500Km!!  Much further than I remember, but that fits with what happened.  And I'm very happy (and relieved) to hear I'm not going to be deluged with alien BB's and endless base defense missions!
