Here's a quick taster of the newly edited episode about Richarda Morrow-Tait's round the world flight.

Oswin is speaking to Emma Easterbrook, the woman who saw that there was nothing commemorating Dikki's world first and was determined to do something about that. The blue plaque which will be unveiled in Dikki's honour is all down to Emma.

It's a nice (though noisy!) introduction to Dikki's achievement. So stay tuned for the full Dikki Redux, out later this month.
