The sensors went white. The 990 did not crash. It did not explode. According to the telemetry, the aircraft simply ceased to be in the air. One moment it was a sixty-ton mountain of Duralumin and titanium. The next, it was a perfect, three-dimensional shadow of itself, painted onto the clouds below.

The “I” in its name was redacted from all official logs. The official story claimed the An-990 project was scrapped due to “metallurgical fatigue” in the wing spars. But the real reason was the flight of November 12th, 1988. It sounds like a heartbeat

On that night, the I--- Antonov An-990 rose from a hidden airstrip near the Aral Sea. It reached operational altitude at 02:00 local time. The ground crew, wearing double-layered ear defenders, watched the altimeter tick past 15,000 meters. The order came over the scrambled channel: “Carrier, this is Hearth. Execute Lullaby.”

The designation was not a mistake, though the censors wished it were. Scrawled in faded blue pencil on the edge of the technical schematic, the index read: I--- Antonov An-990. The sensors went white
