Before we go down another thread of BA slagging can I draw your attention to the initial posting:
"Initially I think they called BA's staff ambulance to attend the scene"
Wouldn't it better to spare the vitriol until someone can confirm that:
a: BA actually own an ambulance.
b: That the crew of such ambulance, if it exists, are actually paramedics and that the ambulance is equipped for emergencies and isnt just a glorified bus for carrying out-patients and walking wounded.
Personally I've never heard of this crack team of BA paramedics, and if they did exist I'm sure we'd hear about them every week in Pravda. Its well known that if a BA pax requires medical assistance at LHR then you have to call a London Ambulance. We don't even have nurses at LHR anymore.
