This is the cover of the latest issue of Private Eye, published before England played its first World Cup match. The England players are shown disembarking from the plane (in Brazil, one assumes). The pilot asks, "Shall I keep the engines running?"
"Shall I keep the engine running?" is a question typically asked by taxi drivers when their fare asks them to wait rather than drive off. It suggests that their client won't be long.
How could they possibly have known that England would be eliminated so quickly? Don't answer!
Note the use of "Shall I" to make an offer/suggestion. See here for more on this.
