Musk and O'Leary clash over Starlink

Elon Musk and Michael O'Leary, the CEOs of SpaceX and Ryanair respectively, are having a big argument.

Musk wants to put his Starlink internet service on Ryanair planes, but O'Leary says it would make the planes use more fuel and cost a lot of money.

They've been saying mean things about each other on social media.

O'Leary said Musk doesn't know anything about planes, and Musk said O'Leary should be fired.

Musk even joked about buying Ryanair and putting someone named Ryan in charge.

It's a big fight between two very rich and powerful business leaders.
