I don't know how old this box of spark plugs is, but somewhere out there someone in charge of marketing decided that the packaging with which to sell their cylindrical product featured a well-endowed woman in shorts. Who knows, maybe it works.
It could be worse. The young lady does have her knees together.
Oh and I wouldn't apologize either. There is no threat anywhere in that comment card. It's rambling, and it's apparently styled after a Saturday Night Live sketch, and it discusses bad things happening to an airplane, but it's clearly voiced as a nervous passenger vein, not as in "it would be a shame if anything bad happened to your nice shiny airplane, capice?" The comment is simply a ridiculously rambling version of, "OMG what if the plane crashes, I'm so scared!" The commenters on the online article all seem to think the note is threatening. Am I missing a cultural reference? If I had been a pilot and the flight attendant handed me that, I would wonder why they bothered, but in the interest of good CRM ask them to send it on to corporate, and offer the guy some reassurance in case he really was afraid of heights. Why WOULD flight attendants open a sealed customer comment card, anyway? So they can throw it away if it is critical of them?
