Dan - indeed - a point I made a while back about the ripple effect of a MAYDAY. It is inevitable and must be very uncomfortable for ATC.
By the way, crews should ALWAYS have enough fuel to perform a g/a and second approach - in or out of LVPs - they may well then be into PAN or MAYDAY because of the legislation, but certainly in LVPs they should always have approaching at least an hour's worth of fuel in tanks at g/a at destination unless the circumstances are extreme
A little like the cross-filing of LGW/LHR by Big airways, where you could have a/c going round at LGW to divert to LHR with a/c going round at LHR to divert to LGW. Loads of fun there for ATC!
