The grimaces on their faces said it all, reinforced by what no doubt soon will be sore backs, arms and legs: It ain't easy pulling an airplane.

Yet more than 500 not easily intimidated people turned out Sunday morning at Atlantic Aviation, adjacent to Philadelphia International Airport,  to take on a hulking, 75,000-pound Gulfstream IV to raise money for Philadelphia's Ronald McDonald House.

The ninth annual PRMH Plane Pull, sponsored by Allstate Insurance Co., raised more than $170,000. Forty teams took turns pulling the aircraft 50 feet, each trying to finish with the fastest time. Those honors went to team Pull My Finger (what a witty crew), which pulled the plane in under 13 seconds.

The plane was donated by Philly Jet Service. Top fund-raisers included Chickie's & Pete's, TEAMPHLY, Aberdeen Asset Management, Walmart, and Owen's Heart Heros. Ronald McDonald House helps families of seriously ill children by providing them with a place to stay and a community of support.
