The NASCAR team initially loaned one 45-passenger plane and an eight-person crew to Missionary Flights International, but gave a second aircraft and additional personnel because of the desperate need.
The Hendrick flight crews have been taking supplies and support teams into Port-au-Prince, and reacting onsite to situations.
Team owner Rick Hendrick said Wednesday that one of the planes transported 26 orphans to Fort Pierce, Fla., on Tuesday to meet American families that had adopted the children before the earthquake struck.
Hendrick is covering the cost of the flights.
Others in the stock car community have also raced to the relief effort for the earthquake victims.
ARCA owner Andy Belmont will give all money won at the season-opening race at Daytona International Speedway to the relief effort, and several tracks have started relief programs.
The Auto Club Speedway and Indianapolis Motor Speedway are raising money to support the earthquake victims.
"Hope for Haiti" at Auto Club raised money to the American Red Cross. Race fans were able to drive through the two-mile speedway and drop off a check.
At Indianapolis, the speedway is working with the Red Cross on an online auction.
CHILDRESS CUTTING BACK: Owner Richard Childress will start the season with only three cars.
Since he couldn't find sponsorship following the loss of Jack Daniel's, Childress has parked the No. 07 Chevrolet and driver Casey Mears .
With Mears on the sidelines, Childress will have cars driven by Kevin Harvick , Clint Bowyer and Jeff Burton at the Daytona 500.
TRUCKS BACK AT DARLINGTON: Chris Browning is hoping the return of NASCAR's truck series to Darlington Raceway this summer will lead to a longer run than the last time.
Darlington officials announced Wednesday that the track would hold the "Too Tough To Tame" 200 on the night of Aug. 14.
Set up, inspection, qualifying and the race will all take place that Saturday.
Darlington had initially tried to attach a truck race to its Southern 500 show over Mother's Day weekend.
However, schedules had never worked out, Browning said.
Darlington got an opening when the truck series decided not to run at Milwaukee this year, and Browning pounced on the chance to light up the track for a second event.
