Matched on timing alone, against the windows the warning itself states — a launch counts if it lifts off inside one, or within the hour before it opens, which is where a disposal burn usually falls. No launch pad is near this area (down-range debris and stage-disposal zones are typically an ocean away from the pad), so this is a hint, not an identification. Data: Launch Library 2 (The Space Devs).
