As more and more unique marriage proposals hit the web, the proposals keep getting even more creative and elaborate. In this case, Lisa had no idea her boyfriend Dave had anything to do with this helicopter ride until they landed on a mountain and he proposed to her.

To make this happen, Dave had to enlist the help of multiple helicopters, several video cameras, photographers, a model to trick his girlfriend into thinking she was going out as a stylist for a modelling photo shoot and who knows what else.

The crazy thing is, almost everybody donated their time and talent for this spectacular proposal and incredible video that captured it. Let's just say, Dave definitely has friends in high places.
