Gosh, just when everybody is talking about what a glamorous, enjoyable experience fllying is these days, it gets even better.

A Chinese airline has calculated that it takes a liter of fuel to flush the toilet at 30,000 feet, so they’re urging passengers to get in the airport bathroom line before they get in the boarding line.  Or,  you might say, “mind your pees and queues.” 

The energy used in one flush is enough for an economical car to run at least 10 kilometers, one pilot was quoted as saying.  

This is going to be fun. On the one side you’ve got harried flight attendants trying to keep passengers from wasting the sanitary facilities,  and on the other you’ve got a plane full of people who have been drinking coffee and beer for three hours.  Who do you think is gonna win?
