Overheard while flying across eastern Texas today:
Air Traffic Controller: “Cirrus 823RC, switch to Houston Approach, 124.25.”
Cirrus 823RC: “Roger, Houston Approach, 124.55.”
Controller: “Cirrus 823RC, that’s 124.25.”
Cirrus 823RC: “Roger, um, 124.35. No, 124.25. Sorry about that.”
Controller: “No problem. Math is hard.”
