150000 lbs each.

I’d gotten bumped and rebooked twice for flights yet was going to miraculously end up flying cross country AND make it to my destination 5 hours earlier than scheduled. The gate agents had still put me in advanced boarding so I boarded with wheelchair bound fellow passengers. Two ladies above 70s settled in next to me for the short puddle jump. And I began to wonder how I’d get out of my window seat at the destination ahead of them.

As the mother and daughter talked, I stared out the window, marveling at how close the Vegas strip was to the runway. It was then the daughter pointed out one of the tugs to the mother.

“Ma, it’s been 20 years since I made one of those “

Made?? I eavesdropped further; my eyes no longer focused on the strip.

Yes, the last one was for the 777s and boy those are heavy. The trailer bringing the weights for the first one twisted and broke apart when taking its first turn.

Now, I was really listening. I’m a sucker for all things airplane.

Yes, the tugs ordered for the 777s are 5 times heavier than those pushing our “little” 737. Each weigh about 150,000lbs to push the plane.

Without thinking first principles, why? I wondered aloud, betraying my silent eavesdropping.

She knew.

The nose of the aircraft carries nearly a sixth of the plane’s weight being pulled down by gravity. To counter those forces, the tug has to apply at least that much force. At a 90-degree angle to gravity, even more.

By now, I’d forgotten my reason to rush out of the aircraft upon landing. I’d even stopped wondering when our tug would arrive at the plane to push it back from the jetbridge. I was now simply mesmerized by the stories told by this retiree, my seatmate, who loved driving from Ogden UT to Las Vegas to see her sister regularly. On a plane this time because car rental and fuel were more expensive than the plane ticket.

Luckily for me, I was seated next to her due to my own set of circumstances and learned something new about airplanes, airports, and even the tugs.

What was the hurry to deplane again?
