In a world where the most intimate human experiences regularly take the form of viral videos, one man went sky high to propose to his girlfriend. 

He made their love soar by popping the question aboard Stealth, a super fast roller coaster at the UK's Thorpe Park that goes from 0 to 80 mph in just 1.8 seconds. 

Sounds like they had a right blast.

Okay, we'll stop now. 

Cue the jokes about their relationship only going downhill from here...
