I used to fly on L1011 with ckt ........ but they very much showed their age ........Having an underfloor galley(ufg) had its good and bad points ... good points if you worked down there it was large and roomy with 2 good windows which looked down rather than out ..... also it was quite peace full compared with upstairs ......On the bad side CAA regs stated that only a certain amount of carts could be at cabin level at any one time ... therefore when drinks service finshed all drinks carts had to be sent downstairs .. you would start meal service ..... passenger in 44A would ask for wine .... off you go down to doors 2, down in the lift get wine from cart back in lift back to row 44 ....... passenger in 44B then says ummmmmm I would like wine as well ... so you can see it was very time wasting ... when on a PMI . Also aircon was not that good cool air would condence on ceiling and on take off pax sat at rear would get a shower ... also carts on L1011 were very very heavy compared to modern ones ... but did have fun 11 cabin crew on routes to middle east , india .USA ,carribean .. good old days !!!!!!!!!!!!!!!!!!
