You said "Therefore, I must agree with Tapper's Dad; the AAR system, No.7 tank and the SCP are "unsafe" until proven otherwise, and isolation is not the answer. Safety has to be proven by evidence, not by the lack of it".
I find it interesting that after the incident on 22-11-04 when XV227 returned with fractured hot air pipe in SPC and a "cooked" No.7 tank were there was proof of the fault they continued to use No7 tanks and the SPC.
And yet after the crash of XV230 they stopped using No 7 tanks and the SCP and stopped AAR yet there is no proof as yet that any of these caused the fire or explosion. Why did they not do this things after the XV227 incident.
