All of this mess on Wales could have been avoided if they did as I've suggested and joined forces with N.I. between 8:05pm - 9:00pm to keep the show on the road in 2 out of the 4 Nations.
I’ve not worked in playout, but do have career long experience on live radio and TV news coverage in studios and on location.
What you ‘could have’ done is very different to what you ‘can do’ in any given situation, especially when your sole focus is to try to rectify a situation and / or keep things going.
Procedures and plans are useful to know or have close at hand, but in the end those involved have to make the best decisions they can under pressure.
Unless you know the exact circumstances, nature of the fault / problem or were there are the time, you have no basis for coming up with a fantasy schedule of what “could have” been done.
Especially when writing a forum post after the event whilst sitting at home.
