Ok, excuses time.
Last time I looked at the practicalities of a sensor warning system was about 17 years ago when someone excited about MegaTrav wanted to GM a campaign.

My knowledge of CT in this respect was never 100%.

What I remember us agreeing is that a system- wide system was too expensive. A planetary sensor system was going to cost so much that defended were going to be rudementary. All this may have changed in T4 & 5.

Never assume the obvious is true.

Border? You mean boarding?

Confirm how?

Assuming there is a gas giant in the system?

And if my force conforms to traffic control patterns?
