It might just be the most difficult, but most rewarding tug-of-war game around.

Friday, Delta Airlines held its annual Jet Drag competition, in support of the American Cancer Society.

Teams of 20 competed against each other at Delta's Tech Ops Facility in Atlanta.

To be declared winner, teams had to pull a 167,000 pound Boeing 757 jet 20-feet.

Also competing, was former Atlanta Falcons player Chris Draft, who said he has a personal connection to the cause.

Officials said a record number of teams competed Friday and more than 3,000 people attended.
