Hasn't JOIN! (or rather: its website) been around for something like 3 years with nothing happening at all?
By the way, I am just spending my 8th hour of the day in the LCY departure lounge as LCY was closed down by fog almost completely until noon. It seems a few inbound planes diverted - one or two Cityjets, the Sun Air Billund flight and possibly also two Alitalia E190s (as they touched down almost immediately after airport re-opened). Did any of those end up in SEN? (LG went to STN and the BA A318s to LGW, but no other diversion airports were given).
