Thank you Ed,
I read somewhere in the accident report about the fuel migrating to outside of the skin and along the fuselage, and whilst I can see that the direction of the fuel travel would be against gravity and airflow, I was more interested in the remote possibility of fuel getting into the jet eflux during AAR when, the aircrafts attitude is 'nose up' (if I remember correctly) and the various wake turbulances and vortexs generated from the tanker can cause unusual airflows and currents?
Thanks for the explanation.
