There were four LCY diversion on 24/09/12 (which I assume is the day referred to by Magnus Knight), these being 1 x Cityjet RJ85, 1 x BACF E190 & 2 x Cityjet F50. I don't have the times for those but it's certainly possible they arrived in short order so there could have been some delay in disembarking the pax. Mind you people do have a tendency to say things like "for what seemed like hours" when it was perhaps 20 minutes don't they?
This morning's SEN-ALC diverted en route into LGW with a pax medical emergency this; let's hope there's a happy outcome to that incident.
Happy New Year everyone.
