Santiago,
You may be splitting hairs but are correct in your comments regarding crew procedures. This was a case of the crew, and particularly the Captain and Flight Engineer, using excellent judgement to monitor the bomb bay during the AAR.
As for speculation, there are plenty of non-specialists, but also a handful of "specialists", making comments regarding the safety of the aircraft. The SCP and bomb bay heating may have been isolated, but until the BoI release their findings none of will know the source of ignition.
Until then there remains serious doubt in my "specialist" mind regarding the safety of the aircraft.
