Community Initiatives

We love contributing in whatever way we can to local schools, programs and community initiatives. Especially when Chinooks are involved.

“We believe the children are our future” isn’t just a line in a Whitney Houston song, it‘s also a big part of our community initiative. That’s why many of our contributions include supporting the local schools’ cheerleading and athletic programs as well as an after-prom initiative designed to protect our kids from drinking and driving on prom night.

We’ve also donated our capabilities to the construction of the Little Mule Trail, a project resulting from the combined efforts of the Lathrop Garden Club and the Lathrop Elementary School.

An ING CH-47 prepares to set a bridge in it’s new home. DCSI removed and prepared this bridge for transport, and performed the final placement and restoration as part of a training exercise for the Iowa National Guard, who flew the bridge to their new home using a Boeing CH-47 Chinook helicopter.
