Unclenelli,

The Dips is not a problem (as AP would seem to already know) . These would have been dip'd under the standing no-notice authority by the DA/Amb level across France, Italy and Spain, Tunis would have been even higher!).
STS/ATFMX STS/HUM STS/HOSP would have been applied to these flights in the FPL (since 2005, BZN have been able to self-auth under licence, meaning no CTOT aka Slot-time from EuroControl.) (GA-PPruners WARNING - Audits are regularly checked to ensure paperwork is in place, with fines for those who haven't!)
My experience is in the civilian AA system. My comment was referring to airway clearances not diplomatic which I suspect was expedited at government level. As you say in such an incident you treat the injured and sort the rest out later same as any mass civilian casualty situation.
As always the 99 Squadron the people at Brize and the Regiment showed the RAF at it's best.
