Your support helps us to tell the story

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.

The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Your support makes all the difference.

Sir: The incident involving a passenger jet and a light aircraft at Birmingham Airport ("Wings overlap in jet's near miss", 9 September) appears to have been due in part to a misunderstanding over the radio frequencies involved. In view of this, is it not possible for the radio frequency used by the aircraft to be changed automatically by a signal from the ground? The technology required is well established. It has been applied in cellular mobile systems for some 30 years.
