This entire story made me laugh. In a lot of ways this is the same way that many old houses are supported with the main difference being the house takes up less square footage. Racer has been like this for years (probably it's whole life) and was just waiting for the right person to come along and make a big deal out of it.
Now wait until they learn how much coasters start leaning and flexing 😂
I've never been on a full 90 degree tilt coaster but even the slightly sloped one I've been on actually gave me more of a thrill than any holding brake on a B&M dive coaster (like Valravn). Being held at 90 degrees and then suddenly being dropped is going to be something unlike anything you've experienced on a coaster..... This will be on the level of a drop tower. One of these has existed overseas for decades and I've been dreaming of riding it.... I seriously can't wait.
