Question: Where did an accident related to spaceflight that involved a rocket which was cancelled after decades of development happen ?

text: List of spaceflight-related accidents and incidents
Non-astronaut fatalities -- Fatalities caused by rocket explosions
This list excludes deaths caused by military operations , either by deliberate detonations , or accidental during production - for example German V-2 rockets reportedly caused on average an estimated 6 deaths per operational rocket just during its production stages . [ 132 ]
This article lists verifiable spaceflight-related accidents and incidents resulting in human fatality or near-fatality during flight or training for crewed space missions, and testing, assembly, preparation or flight of crewed and robotic spacecraft. Not included are accidents or incidents associated with intercontinental ballistic missile (ICBM) tests, fatality or injury to test animals, uncrewed space flights not resulting in human fatality or serious injury, or Soviet or German rocket-powered aircraft projects of World War II. Also not included are alleged unreported Soviet space accidents, which are considered fringe theories by a majority of historians. As of 2020[update], there have been 14 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
