Yeah I wondered that. I assumed either the Doctor retrived them, or else they ejected before it shifted back in time (my memory's fuzzy on the timing)
But yeah, Nyssa's lovely but sometimes you wonder why she's there! I think she gets more to do now Adric's vacated the Tardis...at least until Turlough shows up!
Time-Flight 1

In the aftermath from the previous adventure, the Doctor has returned the survivors from the doomed freighter to their proper time.
At Heathrow, the control tower has lost contact with one of their Concords. As we watch, the airplane disappears from the sky.
Something goes wonky with the Tardis (doesn't it always?) and it materializes just above a landing strip at Heathrow, before moving inside the airport at Terminal 1.
They are quickly spotted by authorities. The Doctor name-drops UNIT and the Brig. Moments later, they are given all but royal treatment.
The Doctor suggests a plan - put the Tardis on another Concord and have it fly the exact same flight the previous one had gone through. He'll use the Tardis to take readings and see what happens. They agree, and the plan is put into motion. The Tardis is put into the hold, Tegan, Nyssa, and the Doctor are the passengers, and there are three pilots. Well, a pilot and two co-pilots.
They land at Heathrow. At least, they think they do. Back at the real Heathrow, they've lost the airplane in the exact same manor as the first one.
On the tarmac, Nyssa sees a group of four corpses, just for an instant. This gives the Doctor an idea. It's all an illusion. If they concentrate hard enough, they'll be able to see reality. And they do. It is the same location as the airport, but about 140 million years in the past.
The Doctor and Tegan spot the first plane and head off with Nyssa and the crew staying behind.
They spot a group of people from the first plane carrying the Tardis. They're under some kind of spell or hypnosis.
The Doctor is enveloped in some kind of bubbles as we fade out.

Are the Ice Warriors back? What, wrong kind of bubbles? Ah well.
It's a fun little story so far, but it makes me wonder how the heck they filmed it. As we all know, the budget was less than satisfactory for this series, but they managed to film on a plane, and use actual planes and such during the episode?
However they did it, kudos to them. Cuz it's pretty rather marvelous.
It was nice to have an explanation for the freighter survivors. They don't do this very often anymore, reference the previous story. It was a nice throwback to the earlier eras.
