Ryan caught the radar tactical superimposed on the head's-up display and slued the big gun barrel around toward one of the incoming jets. They came fast, from near the border. Gaining on the T-bird, which was going full out toward the southern coast of the narrow isthmus. Ryan wasn't sure what Plan Beta was, but one thing was clear; the bogeys would catch up with the T-bird before it reached the coast. And even if they did get to the bay first, they'd be easy to target over the water.
