The fact that qualified personnel are to be in the cockpit goes without saying, as we all know safety protocol is strictly adhered to in this industry.The above mentioned incident did however occur shortly after refueling of the wing tanks so the pumps would have been on IAW procedure, perhaps the low pressure caution light was burnt out it really doesn't take much heat to ignite jet fuel I think thats why it works so well.
Occasionally things are simple, as engineers do we not search for the simplest solution first in an effort to eliminate possibilities?
If you would like to read more log onto this website , most informative.As I said purely speculation on my part but I see the connection.
