St. Louis (KSDK)--Dan Asis met Jackie Uhorchak while both were serving as platoon leaders in Afghanistan.
They fell in love and eventually returned to Fort Leonard Wood.
Dan wanted to propose to Jackie in a big way.
So he decided to pop the question under the Arch, and he enlisted the help of a flash mob.
Dan's friends actually recruited the flash mob on Craigslist. Those who responded had to download instructional videos and arrive at the Arch early on the day of the proposal for practice.
All went as planned, then came the big moment.
Dan popped the question.
Jackie said "yes."
The flash mob cheered.
Jackie says the proposal caught her off guard.
"No I was not expecting it, not in the least, especially not anything this big or this public," Jackie said. "He's been joking for a while that he was going to come up with something really big and really outlandish and he was going to outdo everyone but I would have never imagined this."
