I'm not a tennis fan at all but the ABC's Goolagong serves plenty of drama

The America's Cup win in 1983, or maybe biopics on Don Bradman or Dawn Fraser would seem to be obvious starters but for some reason the film industry tends not to worry about making movies about sport.

Fortunately for sports lovers TV is happy to fill in the gap with plenty of mini-series about iconic events in our history.

A few that spring to mind are the mini-series on Bodyline, World Series Cricket and on Peter Brock.

We could also mention the Warnie mini-series but I reckon it's best we don't.

Now a large gap has been filled with this three part mini-series on the career of tennis legend Evonne Goolagong.

It's a good example of how a sporting miniseries can be full of drama and intrigue and does not just have to be of interest to those who play the particular sport.

I'm not a tennis fan at all but the narrative of the questionable actions of Goolagong's coach, her struggles with racism and ostracism by other female players for not supporting equal prizemoney payouts gives plenty of drama to hold the attention.

NASA wanted everyone to be paying attention to the launch of the Challenger Space Shuttle in 1986.

There had been 24 previous flights of the shuttle and the media and the public had got over the novelty of it so little attention had been paid.

To remedy that the officials decided to put a civilian on board the Challenger, school teacher Christa McAuliffe In the hope that it would create attention.

It did - but it also meant there were so many people watching live to see the tragedy of the shuttle explode shortly after take-off.

In this documentary we hear from partners and children of those who died in the tragedy and also from some former officials at NASA who had concerns about the shuttle even taking off that fateful day.

For many of us who grew up listening to Dr Karl on Triple J every week it's easy to assume that he seems he knows everything there is to know.

He rarely seems stumped for an answer and never seems to need to think before answering a question - it's as though all that knowledge is always there, just itching to come out.

But Dr Karl himself will admit that just isn't true - he doesn't know everything.

I tends to be the case that the more you know the more you realise there's so much that you don't know.

That's the basis for this show - now in its second season.

Dr Karl gets to fill in a few gaps in his knowledge, and get paid to make a show about it.

One of those gaps is how they make meat pies.

Along the way he gives us some interesting facts such as how once upon a time the casing of a meat pie was thrown away rather than eaten and the slightly scary idea that flour is actually combustible under the right circumstances.
