So I'm a lemming now? Thanks for that.
No offense intended. I was really referring to how flight cards "became a thing" decades ago (the old original lemmings), to the point that people just assume it HAS to be done.
It does NOT.
I've run launches with zero flight cards.
If it was a really big launch, things would be different. Want to be sure that the person whose rocket is being launched.... is aware of it. But at a small launch, it's not necessary.
Pretty much, if the launch is not big enough to be using a PA, it's not big enough to need flight cards.
As I said, RC plane fliers don't do flight cards, and if they do any flight logs...... it is either their person flight logs, or a club might require a person to "sign in" for the day. But not get bogged down into paperwork every time they want to take off. At least, that's the case for normal routine flying.
And back to cards, when they are done, keep them as brief as possible for wha tis really needed for the logistics of the launch (and not for people who love to collect statistics, making others jump thru hoops). The kind of info that might be justified for a 2 stage clustered level 3 flight.... is not needed to fly an Alpha on an A for 10 flights with 10 separate flight cards, so don't have "data creep" that requires info that's not really needed.
