Oh yes another thing. The plane was at the gate for over two hours. Great fun watching the cleaners hurling bags of waste and stuff about and guys climbing into the rubbish bins to collect all empty water bottles for recycling . It struck me as very odd that for the whole servicing time the power plant in the tail of the plane was belting out a plume of hot gas--at least there was no soot or smoke--just heat shimmering . How's that for Global warming. Good job oil has dropped in price faster than fuel surcharges. I thought planes usually hook up to mains power by cable these days. Wrong again !!
