That's very nice poem. But look at this couple of sentences.

"and these were the men who worked on the planes
But kept their feet on the ground".

How do we keep our feet on the ground? I have flown in test runs with pilots, and flown to do maintenance to other stations, have flown as a nonrev to many places. I have more air time than alot of flight attendants. Yes, we do keep our feet on the ground as a general rule, but we go airborne too. Some of us have pilots license. (Not me.)
