MR POINT
SAR is being maintained.
There will be two crews designated to cover SAR.
There will be a jet available.
Sometimes that SAR jet, however goes flying to meet other tasks - but that jet and its crew will then hold "airborne" SAR for the duration of the sortie.
When the jet is down then the original SAR designated crews have "their" jet(s) back.
It's a case of using a serviceable airframe for many tasks!
