For the majority of the Supermarionation series, the episodes have a number of different running orders. I, personally, have followed the order in the Supermarionation Episode Guide by John Peel. However this order leads to problems such as in 'Move - and You're Dead' where Grandma arrives on the island for the first time, however she's arranged thermal clothes on 'Sun Probe' and plays a major part in devising a solution in 'Vault of Death'.
So I ask you: What would you consider the proper order of episodes?

In "Edge of Impact", when Col. Casey drops in unexpectedly on Tracy Island, Jeff makes the comment that perhaps it's "...more of Tin-Tin's admirers." This would seem to be a bit of follow-up continuity from Eddie Houseman's visit in "End of the Road", but in fact, "Edge of Impact" was done first. Did the same writer do both, or did they think that "End of the Road" would be done first, or what?

They could probably have "Trapped in the Sky" and "Pit of Peril" and possibly "The Uninvited", and then have "Move--and You're Dead" introducing Grandma. A sensible pairing would be to have "The Perils of Penelope" and "Sun Probe" back to back using the same Sun expedition--one adventure taking place the week of the launch and the second one a week or so later, when they had reached their destination.
