Why don't we fill an Airship with a Vacuum?

The video discusses the tragic maiden voyage of the British R101 airship, which ended in disaster due to bad weather and structural failure. This event marked the decline of hydrogen-filled airships, leading to the use of helium, which lacks the necessary lift for large airships. The concept of vacuum airships is explored, highlighting their theoretical buoyancy but also the immense structural challenges due to atmospheric pressure. Despite past attempts to fund such projects, no material currently exists that can withstand the pressure without being too heavy. The video concludes that while future materials may solve this, the risk of implosion remains a significant concern.
