I still haven't seen it.
The seal assembly in the wellhead was tested to 10,000.
Prior to displacing the riser, a positive pressure test held.
The negative pressure test showed 1,400 psi on the drillpipe and 0 psi on the choke and kill lines. If the drillpipe contained seawater and the choke and kill lines contained mud prior to displacing the riser than this is exactly what the pressure should read.
In the last 120 seconds something let go and the standpipe pressure went from 1,500 psi to 5,800 psi. I can't imagine what the men on the rig floor were going through then.
