Funny that they went laminar and included some heavy drag reduction shaping: weren't they supposed to have no air in the tunnel?

Probably be more realistic to keep it thin instead of complete vacuum.

A reasonably well-equipped laboratory would be hard pressed to create the sort of crappy vacuum you'd find in low Earth orbit...never mind a tunnel meters in diameter and hundreds of miles long with many, many large-size hatches that are constantly opening up to the larger environment.

It was always a low-pressure rather than vacuum design. Musk's initial sketches even had a fan compressor mounted to the nose.

During SpaceX’s annual Hyperloop competition, a pod designed by the Technical University of Munich reached a record top speed of 288mph (463km/h) - but soon after exploded

Note that the video is glitched at the moment, they'll probably fix it quickly enough though.
