Even at hypersonic speeds, that would take some time.

Therefore time in the atmosphere at hypersonic speed would be considerable, possibly 15-30 minutes.

Hypersonic speeds are those above Mach 5, or five times the speed of sound.

The X-15 had a thick wedge tail for stability at hypersonic speeds.

That helps the internal parts withstand the hypersonic speeds over Mach five.

Most of the jet travels at hypersonic speed.

The first stage is then jettisoned and the vehicle re-enters the atmosphere at hypersonic speed.

However, at hypersonic speeds, this model becomes applicable.

If successful, the flight will be the first of an air-breathing, nonrocket plane at hypersonic speeds.

He can reach hypersonic speeds when flying.

The goal is realistic mimicry of hypersonic speeds, more than five times the speed of sound.

The X-43A is the first aircraft to reach hypersonic speeds using an air-breathing engine.

When it comes to re-entry at hypersonic speeds, the properties of gasses change dramatically.

Ashirijen A woman who uses forcefields, manipulates wind, and moves at hypersonic speed.

The Enemy missiles arc over an island to the south, racing at low altitude across the water at hypersonic speeds.

For the first decade he was engaged in aerodynamic research in the high supersonic and hypersonic speed ranges.

This flight simulated a 654-mile (1053-kilometre) cross-range reentry, and banking at hypersonic speeds.

But the recombinant lattice structure had taken the shape of a cutter, its blade vibrating at nearly hypersonic speed.

The A2 would be capable of flying, non stop, halfway around the world at hypersonic speed (Mach 5+).

Some of the collapsing liner goes on to form a constantly stretching jet of material travelling at hypersonic speed.

In aerodynamics, hypersonic speeds are speeds that are highly supersonic.

Companies Three aircraft builders were awarded contracts to try to create a craft that takes off like a plane and booms into space at hypersonic speed.

Hypersonic speeds are highly supersonic.

During descent, the orbiter passed through different layers of the atmosphere and decelerated from hypersonic speed primarily by aerobraking.

Though the definition for hypersonic speeds is not very clear and is a subject of debate among scientists, they have come up with a possible definition.
