Richard,
I have been followling this thread with interest. For a couple reason. I
intend to respond with my thoughts as I'm sure other Board members will
too. As I said earlier in the week to you I have been very busy with the
FBI investigation as well as some personal family issues. I litterely have
not had time to formulate ideas, opinions, thoughts, to do any of my own
research, to discuss with other Board members etc... any of your concerns
yet. I am very aware of grant monies available from NAR and Tripoli. Some
of your comments regarding the Board struck a nerve with me as I'm sure you
intended to do. If I don't respond right away or if a Board member doesn't
respond in a time frame to your liking, I apologize.
My comments and thoughts to your concerns will be forthcoming. Including
the ones you emailed me personally. Please be patient.
Mike Ostby,
ROC President

Hello Jeff! Hey, are you going to ROCstock?
I think this is similar to what James put together for TCC.
Again, I don’t think the Board is interested. Otherwise, I think they
would say something about this.
I know it’s another ‘thing’ but it doesn’t look like it would be difficult
to maintain once set up. And, I also think I saw grant money ($250)
available on TRA’s website for equipment or outreach.
Having this kind of technology wouldn’t be bad to have at a launch, would
it?
I have seen HP rockets launched many times when there are commercial and
small aircraft over the range. But, I’ve been to many ROC launches. Like
at the end of a launch last year. The rocket launched and then we saw the
aircraft. It looked close, but I know it’s difficult to tell from the
ground. There was a long silence while we watched the rocket and the
aircraft. And, how can I say that. Well, because it’s true, and other
people know it’s true. And, that’s the reason to bring stuff like this up.
Anyway, I think ideas that are shutdown immediately with, “OK, then you
get the equipment and do it all the time” have developed as a kind of knee
jerk defense mechanism. I think this developed when ROC became less of a
team and more person dependent.

FYI Flightradar24 makes use of a network of ground monitoring stations
feeding the received ADS-B signals to their server. Here:
https://flightaware.com/adsb/flightfeeder/
You can also build your own setup:
https://flightaware.com/adsb/piaware/build
If there are few local receivers online then your data will be inaccurate,
which includes altitude, course, and ID. I live where the mountains
interfere with the received signals. You often see altitude and course
suddenly change as the aircraft goes in and out of coverage, and sometimes
it will draw a dual trace for the same aircraft. You shouldn't really take
the data at face value, it does require paying attention.
This may not be an issue at Lucerne but might be at more remote locations.
Having a local receiver might help.

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