That might be true dropbear, but consider the launch in a truning engagement...that can surely ruin the day for the launching a/c...fumes going into the engine post launch etc.  I know for a fact that the Adour 871 used by Jaguar have facility for fuel dipping sequence (reduces the ingestion of bad gases post AAM launch) but is there any articles or notes out there that can really explain this phenomenon in the air to air missile launch...Any Jaguar heads out there that launched AIM 9 or IR msl before from overwing pylons?  Thanks
