In this week's show Carlos drones on about maths, Nik talks to us about the logistics of diversions, and Andy teaches us some history! But seriously, we talk about passengers with no seats, hands free bathrooms and how you, dear listener, can go air racing!

And we hear from Eliot Seguin in part 2 of his chat with Nik.
