This is The Guardian.

Hi, it's Helen here. Over the festive period, we are revisiting some of our favourite episodes

of the year. And today, we want to bring you the moving and inspiring story of Khalil Ulla,

whose brother, Mohamed Ayyaz, fell from a plane in London

23 years ago. Earlier this year, he and Guardian journalist Esther Adley went to the spot

where his brother fell in the car park of a DIY store. Despite the tragedy at the heart of

this story, I found this episode an unexpectedly uplifting listen, and I really hope

that you do too.

Every day Rachel walks for hours in Chinganggi, Malawi, to collect dirty water that could make her sick.

For just three pounds a month, Water Aid could help fund a water quality test to ensure water in Chingangji is safe to drink.

when her editor brought over a cutting from a local newspaper.

It was just a paragraph or two about the body of a man that had been found by a supermarket worker

in the car park of Home Base, which is a sort of DIY superstore in Richmond, a quite leafy, quite nice borough in West London.

And the police knew instantly what had happened.

This was an airplane stowaway who had climbed into the wheel bay of a plane,

and at the point where the aircraft lower their wheels at Richmond,

as the approach he threw from the east, he'd fallen out, and this is where he'd landed.

Quite quickly, the police managed to establish what flight he had come on, and it was a British

Airways flight from Bahrain that had taken off the night before.
