The missiles fly low, to avoid most radar, and travel at subsonicspeed.
2
The eggs reached subsonicspeed a kilometre above the land.
3
Despite the sudden cold that rolled across the plains at subsonicspeed, the air wavered and danced as if through a mirage of heat.
4
We've been flying at subsonicspeeds like total lame-o's since the Concorde left service in 2003.
5
The Sizzler starts at subsonicspeeds.
6
If you throw a ball, or shoot a bullet at subsonicspeeds, this model probably works just fine.
7
Yet the traveling public is still stuck at the relatively slow, certainly subsonicspeeds of passenger jets, for now.
8
The earlier Russian tests were hybrid ramjets -slightly different, with oxygen only moving at subsonicspeeds inside the engine.
9
After being launched from an aircraft, the X-51A fires its conventional rocket booster, which builds up subsonicspeeds before the missile's supersonic ramjet kicks in.
