I hear ya unimogbert and understand the concept, I just thought it was humorous.
A saying I do live by, especially concerning flying in questionable weather is; "Takeoffs are optional, Landings are Mandatory".

Humorous is fine but can be confusing to those who aren't in the know.
The one I like is - What are the only things that Lead wants to hear from his Wingman?
"Two's up." (on the radio)
"Lead you're on fire."
"I'll take the fat chick." (sorry, that's the joke)
I was practicing takeoffs and landings last Friday and the field density altitude was nearly 8000'. Someone from the "flatlands" passing thru with the wife and kids and refueled to the top could die trying to takeoff under conditions like that because the airplane will not fly! Happens sometimes here at the foot of the Rockies.
Aircraft have "usable load" figures rather than seat count or fuel capacity. This is to suggest that some days with light planes you can take the family and some days you can fly for many hours but they won't be the same day. (unless you want to be Test Pilot for the final flight) I've been on airliners where passengers were asked to deplane because the field temperature was higher than expected and the 727 couldn't safely go with that fuel/passenger/temperature/field length combo.
Remember that the way the media portray preparedness is pretty much the fidelity they apply to everything else. (i.e. they aren't much on accuracy)
