Gents,
Please don’t assume facts that you don’t know anything about.
QRA a/c are airborne within 15 minutes max.
For this particular msn:
-767 reported its intentions to hold over 4hrs to burn fuel
-the Spanish Air Defence Command then offered the help of a chase a/c (F18)
-once the crew accepted the help, they called a pilot that was preparing another msn for that very afternoon and retasked him and his a/c
There was no need to rush or to scramble the QRA. QRA must be preserved for other defence related msns plus the QRA is armed with missiles and gun while this chase a/c was not.
Please always remember whenever you have an emergency that fighter a/c might help. Radio, navigation, etc... Portugal latest events come to my mind for instance.
