"'My pet peeve is inertia,' says [Ed] Trollope [spacecraft operations 
engineer at technology firm Telespazio VEGA Deutschland]. 'There are many 
good reasons for keeping your engines on in space, but 'maintaining speed' 
is not one of them. If you turn your engines off, you don't stop.'

"Some do it slightly better than others. 'I'd prefer not to single out a 
single film/book/series for this particular error, because it's so common - 
but I will laud the old television show Babylon 5, for doing a wonderful job 
of representing the mechanics of spaceflight inertia so nicely,' explains 
Trollope."
