I always like breakdowns where there's nowhere to hide. Or to put it less sinisterly, when the channel holds his hands up and is completely transparent about what's going on. To put It one way, it "humanises" the channel when they're not pretending to be a flawlessly well-oiled machine. Long gone are the days of "we're just moving the film to another projector" and instead we have moments like when The One Show was taken off air due a fire alarm and the CA
inconspicuously blamed "technical problems". The BBC regions are a little open when things go belly up, but I feel Network are far more "It's okay, just give us a minute, please don't go away!"
Some old clips from the Broom Cupboard are prime examples of what I mean. The first one shows Andy Crane frantically controlling the desk to get himself back on air when a transition to Neighbours goes belly up before he openly asks whoever's next door if he should carry on. The one below has Debbie Flint met with a dodgy projection of Rocky and Bullwinkle and you can actually see whoever's on VT
trying to fix it on the monitor in the background.
