Reminds me of when the nuclear lobby tried to put across the idea that the Fukushima disaster was proof of the safety of U.S. nuclear technology.

Wikileaks lists spaceflight accidents and incidents.

Number of debris objects regularly tracked by Space Surveillance Networks and maintained in their catalogue – About 28160

Estimated number of break-ups, explosions, collisions, or anomalous events resulting in fragmentation -More than 560

Total mass of all space objects in Earth orbitMore than 9300 tonnes.

NASA slams rocket risk, The Age, print version 10 May 2021,   Remnants  of China’s biggest rocket have landed in the Indian Ocean,with the bulk of its components destroyed on re-entry into the atmosphere according to Chinese state media., fencing days of speculation over where the debris would hit….

The coordinates given by the media yesterday,  citing the China Manned Space Engineering Office, put the point of impact west of the Maldives archipelago.The Long March launched last week was the second deployment of the 5B variant since its maiden flight in May 2020 last year pieces from the first Long March 5B fell on Ivory Coast, damaging several buildings.

During the rocket’s flight, Harvard based astrophysicist Jonathon McDowellsaid the debris zone could have been as far north as New York, Madrid or Beijing, and as far south as southern Chile and New Zealand.
