The silence is expected. SpaceX stated that the explosion occurred when the Superdraco rockets were fired and that the capsule was on a shake table, simulating a rocket exploding underneath it.
The capsule is in a million pieces and the area is still toxic, so patience is required.
True. This is a big reason why I FULLY support NASA's investigations into so-called (by them) "Green" rocket fuels. Hypergolic fuels - at least in their present forms - are nasty, nasty substances. NASA & SpaceX should have to disclose the volume and wind-drift of the explosion-caused hypergolic fuel cloud.
so patience is required.
True. But then that patience needs to be extended to the upcoming Cargo Dragon Launch. If the root cause was in a system shared by all Dragon capsules, that puts the ISS and its crew at risk.
