It’s good to hear Gregg’s and David EW’s comments. Maybe even David Smith’s
comments. :-)
Kurt, Allen, Mike, all understand me. I know that James has been in my head
and that must have been a scary experience. Anyway, these guys don’t get too
ruffled by what I say. Fortunately, they know my intentions (because they are
big guys) and the awkward way that I present myself at times.
So, there will probably be spotters and vigilance and lots of teamwork at
ROCstock that’s about 11 days from now. You will all prove that I’m wrong, and
I will love every minute.
I measure the importance of things by not only the chances, but by the
consequences. When something happens, like a rocket coming down ballistic in
the spectator area. Please take the time to try and determine why and prevent
it. Not, “I didn’t hear it hit metal, is everyone OK?, now going to the middle
row.”
There will always be risk, but for some things there needs to be a definitive
solution, not just acceptance.
See you at ROCstock. Now I have to take extra beer money.

I've always been a big one for making sure we don't launch if we see, or
hear, an aircraft flying over. It's not just the rules, it's that I don't
ever want to have to worry about someone in a low-flying plane being able to
take an iPhone shot off what looks like a rocket being fired at them (even if
it couldn't possibly have reached their altitude). There's too much at stake
(for the hobby) in my eyes than to treat it otherwise.
I'm probably considered a pain in the butt by some (okay, maybe more than
'some'), but if I hear a plane over the playa, and I see an LCO arming the
controllers, I'll start yelling 'HOLD' as loud as I can until we can identify
the aircraft and make CERTAIN that it's flying away from the playa, or at an
altitude that it can't POSSIBLY be able to take that 'bad photo'. I know for
a fact that some folks have gotten upset with me for that shout-out, but at
least 25% of the time it turns out that there IS an aircraft in the area that
we have to wait for, so I'm willing to put up with the nasty looks the other
75% of the time...
Just last month (April launch) I was LCOing for a brief while, and at one
point I realized I had just launched a mid-power rocket as an aircraft went
overhead (I'd guess around 3000' AGL). There wasn't a chance of the rocket
hitting the plane, but there certainly WAS a chance of someone getting that
'bad photo', and I was upset with myself for not having seen the plane
beforehand. BTW, nobody commented on the plane until after I'd pushed the
button, either (I certainly would have appreciated it if someone HAD yelled
'HOLD' at me).
...and we haven't even talked about the flip side of the coin. I'm ticked
off at the pilots who choose to ignore the NOTAM that we call in for our
launches and either decide it doesn't apply to them, or they're too lazy to
check things out in the first place. We have, after all, been warning all
the pilots consistently for years about the launches -- yet we still get more
than our share of idiots who think it's 'cool' to see the rocket launches up
close from the air.
Now, do I think we need to have some sort of 'aircraft warning system' in
place other than our own eyes and ears? Nope. I just think we need to apply
the eyes/ears a little more conscientiously than we have been (and as you'll
note by my story from last month, I include myself in that...).

I, for one, would like to hear from everyone that LCOs on a consistent basis
as to how big an issue low flying aircraft has been for them.

Richard, since you just brought this up yesterday on the chat, I’m not sure
if anyone on board has had time to think about it. I, for one, have been
building rockets for ROCStock!
Are you concerned about commercial traffic or private/GA aircraft?

Thank you for the info James. I don’t think the ROC Board is interested
in this at the moment. I’m going to use the flightradar24 app that Andrew
suggested. It’s interesting just watching the air traffic.
And, no, I wouldn’t watch the screen during a whole launch. But, before I
launch a rocket of mine, yes, I would check the app first. And, I want to
learn more about what it has to offer.
Just check out air traffic around the Hawaiian Islands with the eruption
on Hawaii. Interesting stuff, but sorry, going OT.

I didn't spend the launch monitoring my screen at LDRS.
And ... I spotted 4 airliners in our area at LDRS (two UA, 2 AA), all at
FL30 above us.
Maybe you saw the ADSB setup that David brought to LDRS, similar but
better UI.
I keep mine under the table. I also modified the code to alert me when
something is within 4nm
of our launch site. I can give you the patch if you're interested.

Easy and cheap, and if you want to spend the entire launch sitting and

ROCstock would be a great launch to test it.
See how much useful information you actually get and report back.
