Manchester
There was a news item a few weeks ago that mentioned that Manchester airport uses 3 million Litres per day. But only holds 4 million in storage. (There was some pipeline problem and they were asking for as many flights as possible to fuel up someplace else) It mentioned that it takes 12 hours per day to pump the 3mil into the airport.
To do this by tanker would have to be a logistical nightmare. Not to mention the extra wear and tear on the roads.
Would like to know the numbers for LHR.
