This is a total mystery.
I didn't know what a stint is (you do now!), but it seems to be:
- a person's fixed or allotted period of work.
"his varied career included a stint as a magician"
synonyms: spell, stretch, turn, session, term, shift, tour of duty
- imitation of supply or effort.
"a collector with an eye for quality and the means to indulge it without stint"
But I fail to see the relation with the BBC and accidents and mechanical failures, the context of this thread and why you mention me.
Tough way to do it. Looks like mechanical failure, but it was disturbing to read from the BBC that so many "accidents" over there involve people in a hurry; bypassing the gates.
