Some context re. reported speed of #NorthKorean #missile:
All #ballistic #missiles are #hypersonic (faster than Mach 5) at some point in their flight. N.Germany’s V-2, deployed Sept. 1944, was hypersonic during its boost phase. Intercontinental ballistic missiles (#ICBMs)… 1/n

…, first deployed by the US in 1959, are high-hypersonic (Mach 25) throughout their entire flight. Subsequent decades have witnessed the emergence of “#hypersonic” #missile systems that can maneuver instead of following a fixed parabolic trajectory, including #ASBMs, #HGVs… 2/n
…and air-breathing supersonic combustion ramjets (#scramjets). The US investigated maneuvering re-entry vehicles in the late 1970s, the #SovietUnion #HGVs in the mid-1980s; both failed. In 1981, the US fielded the #PershingII medium-range #ballistic #missile (#MRBM), whose… 3/n
So they’re removing the reversing element from HGV tests to make them easier to pass?
I don’t know who needs to hear this, but there’s only one way to get on a loading dock, and it ain’t forwards.
What could possibly go wrong?

I want to add a clarification here, as the Sky story on which my tweet was based my not have been the whole story.
Reversing is to be removed from the DfT examined test but will be ‘tested by a 3rd party’.

I’m not quite sure where an army of competent 3rd party examiners will come from, how standards will be upheld and overseen, or how the funding of this works.
I fully appreciate something must be done to solve the crisis, but safety must remain the number one priority.
