     Government... unions... industry... we have had enough. We - no, YOU - are sleepwalking the rest of us towards a less busy, less relevant industry with a smaller workforce, fewer passengers, fading importance, declining investment, poorly-paid jobs, and a truly shambolic reputation.

Other rare inflected forms, such as sleepswalk, sleptwalk, and sleptwalked, exist, but are nonstandard conjugations.
