How do we find out when LDRS will be near where we live? I live in Calfornia and would be willing to drive up to 1,000 miles away to go to it. I'd like to know how to find out more. I've always wanted to go.

The Bonneville Salt Flats are within a day’s drive of California. We’d love to see you join us for a few days of high power. There’s nothing like the sound of a high power rocket reflecting off the salt. And the recovery area is flat and huge.

I had a thought about the words that make up LDRS, actually the word, "dangerous". In some ways it should be heeded as a warning to those stupid enough to try some of this in a local park. With all the info on the net is is possible for someone to home brew some rather large motors. I think we need to keep the word dangerous in mind so people will continue to respect the power in some of these motors.

Take a look at the RC world and see what is happening simply because people behaved irresponsibly with their drones.
 
LDRS Addition. The photo to the left was my 169 motor cluster record attempt. 168 A10-0t, 1 C6-7. I power. at LDRS-1. The Slobovian Avenger below, was Two records in one at LDRS-2. Full J power with black powder and it had three Cinerocs on the little bt60 pods. Motors: 12 D11-9, 20 D20 (FSI), 20 E5 (FSI) delay was too short but the rocket and all the Cinerocs recovered safely. It took some persuasion to get the range safety officer to launch this rocket due to the inherent dangers, cinerocs cannot be turned on remotely, Herb Desind an I had to stand next to the rocket and turn them all on a t minus 3 sec, with a half pound of black powder under the rocket in the flash pan... Not mentioned above, was my Short lived company, High Altitude Research and Design. HARD... coined from Moose Lavigne's signature saying for an awesome flight, "it was a real HAAAAAARD on"....I made a small number of G and H motors, including the first black smoke motor since the FSI thunderbolts. ThunderJet Macrothrusters. My unique grain geometry, part core, part quad slot gave a relatively neutral thrust curve. This grain geometry was utilized in an Industrial Solid Propulsion commercial motor for Orbital Sciences Space Data Division that went into space. The Viper V Motor (data not publicly available) The motor is about 7" diameter and has approximately 30,000 lb-sec vacuum total impulse.

I went to an LDRS in Lucerne Valley a few years ago and saw a 4"+ diameter, 3' long+ fiberglass rocket, with a doll attached, bury itself two-feet deep, just 10' from an RV with kids and 20' from my new car. EVERYONE was laughing! That was the last time I flew a rocket.

CONTINUED . . .

Then, late one night a couple of months before the launch, I received a rather nasty phone
call from a very PO’ed then-editor of the magazine, Chris Tavares, questioning me about
the true nature of the launch. So I told him. Needless to say, he was not pleased. After
that, they ran a disclaimer in the next few issues warning about "intentional amateur
activities" and urging NAR members not to attend.

LDRS-1 Sport Launch, 24-25 July, 1982, Medina, OH
(SNOAR). Three unofficial “events,” prizes to be awarded
(no national contest points). Contact: Chris Johnston,
26481 Shirley, Euclid, OH 44132; (216) 731-3839.

LDRS-1, previously appearing in this space has been
determined to include intentional amateur activity not
announced in the original notice sent to the Model
Rocketeer. NAR members are urged not to participate
in LDRS-1

-From Model Rocketeer, June, 1982, Con Calendar

We were under a great amount of pressure from the NAR officials, after all, in their
arrogance they thought that they were in control of all model rocketry (at the time even
Estes bowed down to them) and here was someone who was organizing a launch to
publicly do what they specifically forbade. This was something that they never had
happen before. Frantically, Pat Miller, the president of the NAR at the time offered to
send me a list of all active NAR members so I could check to see if the attendees were
members and forbid them to fly. Yeah … right! NAR officials attempted to coerce
certain members that they knew would be attending, asking them to write down names,
take photographs, and generally "rat" on everyone that was there. To the best of my
knowledge, no one volunteered to fink either before or after the launch.

LDRS-1 as well as LDRS-2 through 5 were all held on a farm field near Medina, Ohio.
And not a real great flying field, either. There were houses nearby and lots of trees a
short distance from the launch site. “So why did we launch there?” one might ask.
Simple! The field was owned by Mike Wagner, who was a member in the local NAR
section (SNOAR, or the Suburban Northern Ohio Association of Rocketry). It was
actually listed as a private airstrip, so it was uncultivated, smooth, and big enough for
most model rocketry activity.

LDRS-1 went off without a hitch. People came from all the surrounding states and one
as far away as California to attend. There were a grand total of 47 people at the launch.
Not 47 flyers, 47 people! For launching hardware we had the SNOAR model rocket
racks and one launcher with interchangeable rods up to ½”! A far cry from the launch
range at LDRS today! A lot of FSI E and F motor clusters were flown, along with
clusters of D12’s. Left-over Composite Dynamics motors were flown, along with
Plasmajets and SSRS motors. The highlight of the launch was rockets flown with single
composite Rocket Development Corp. H and I motors! Wow!

After the launch, the club newsletter, SNOAR News ran an article on LDRS-1 complete
with pictures. As a result, every NAR members pictured was contacted by NAR officials
about alleged "safety code violations," and several were expelled after so-called
“disciplinary hearings”.

With the success of LDRS-1, plans were quickly made to continue the launch. More
launchers were added and better crowd control was implemented. The following year,
more people came from the west coast, notably Gary Rosenfield and Korey Kline.
LDRS-2 featured the first composite J motor flown at a LDRS, courtesy of Scott Dixon
of Vulcan Systems, who attended, which was flown by the author. It also featured the
first power shred at an LDRS, also by yours truly. Korey Kline flew a bunch of his high power
Ace Rocket kits. Aerotech flew a number of prototype high-rate motors.

In the next two years, the NAR zealots tried every which way to prevent LDRS from
happening. They threatened to contact the FAA to check the waiver (I told them to go
ahead), got in touch with the Medina city prosecutor, fire and police departments, even
the Bureau of Alcohol, Tobacco, and Firearms (otherwise known as the ATF), in attempts
to shut it down. They failed.

Each year LDRS got bigger, the motors and rockets got bigger, and the NAR saw its
senior membership shrinking as more and more of them left model rocketry, ceased
model rocket competition and entered the high power rocketry sport.

By the time LDRS-3 rolled around, the NAR was forced to admit that we might be right
and started the first "Blue Ribbon Commission" for the study of high power rocketry. Pat
Miller attended LDRS-3 to observe and walked away very impressed with what he saw.
At one point during the fist day’s activities, I offered to let him launch my rocket with
clustered F100 motors, but he politely refused. It was only 150n-sec ! Later, he told me
privately that the degree of craftsmanship that he saw at LDRS, along with the way
the range was operated was better than any NARAM he had been to.

Negotiations began after that with the HPR/LDRS committee, which had such notable
high power people like Chuck Mund, Jim Dunlap, and SNOAR members Chris Johnston
and Bob Geier. Guidelines were drawn up by the committee, along with a proposed
safety code, and submitted to the Commission. Experiments were conducted by Trip
Barber to ascertain the power limits of the new composite motors. Some high power
manufacturers, including North Coast Rocketry, were contacted to give their input in
certain subjects, such as motor design and airframe construction. Others donated
materials for the testing. The Blue Ribbon Commission gave its findings, and out of this
came the new revised NAR/HIAA Safety Code, which was undoubtedly the most
profound change in the hobby since its inception.

At LDRS-4 the crowd on the field was exceeding 100 people. It featured the first
Aerotech K motor flight and the first L motor flight, another Vulcan Systems motor in a
minimum diameter airframe, which we never saw again.

Soon after this, the so-called "Son of Blue Ribbon Commission" was formed to study the
true LDRS type of rockets, over and above the 3.3 pounds which were now called Model
Rockets. Members of the Commission visited LDRS-5 and were impressed by the
quality of workmanship of the rockets, the reliability of the motors, the vehicles in flight,
and especially the strict safety rules which were enforced at the meet. The result of this
was the new NAR code for high power rocketry which allowed NAR members to fly
high-power rockets beyond the 3.3 pound weight limit.

After LDRS-4 we realized that because of motor and vehicle development, we had far
exceeded the limitations of the flying field, and for the next year there was an attempt to
hold LDRS-5 at El Dorado Dry Lake near Las Vegas Unfortunately, the FAA waiver
was refused and hastily plans went ahead to hold it once again in Medina.

Unfortunately, LDRS-5 was the last national high power launch to be held in Medina, as
the field we flew on was leased to a local farmer soon after that and plans were made to
plow it for crops. As a club, we had just one more high-power sport launch there, just a
couple of months after LDRS-5. I’m sure that we probably put a few rockets into the
Medina town square, and I think that we were really beginning to scare the locals!

Also, after the problems that happened that year, both on and off the launch range, I was
reluctant to organize any more events. Several people had attempted to use the launch to
further their personal and political agendas and I became very discouraged, not to
mention, totally burned out. Furthermore, North Coast Rocketry, the company that I
founded and was operating out of my house was consuming increasing amounts of my
spare time. With the request of Tripoli officials, I allowed the copyrighted term "LDRS"
to be used by the Tripoli Rocketry Association for the name of their national launch.

Others have followed the example that was started by LDRS and have organized other
regional type events, some with more success than others. LDRS-6, held in Hartsel,
Colorado, was the first national event sponsored by Tripoli in conjunction with Vulcan
Systems, Inc.

I would like to believe that LDRS was a deciding factor in the Model Rocket Safety Code
change, and that it was also a factor for the emerging interest in high power rocketry, as
with LDRS came the development of many of the leading high power rocketry
companies that changed the face of rocketry as we know it. Never again would we think
of Estes-type model rockets when discussing rockery, Motors evolved from 13, 18 and
24mm “toy” black powder motors to 2,3, 4 inch diameter and larger professional
expendable and reload-able composite motors. From clusters of D12’s to clusters of M
motors. We now have a variety of “alternative fuel” hybrid motors. Rockets leaped from
ounces, to pounds, to tens and then hundreds of pounds. From paper and balsa wood to
fiberglass, carbon fiber and Kevlar. And there is no end in sight.

LDRS was the first, and set the example for others to follow. I can only hope that the
number of high power launches continues to increase all over the country, as the sport of
high power rocketry continues to grow

I urge the sponsors of future LDRS's to continue the tradition of well run meets stressing
safety, as LDRS is the standard all others are judged by.

I remember those days! I was in NOVAAR and Chris was our president!
 
So, what, if anything, did Chris Tavares tell the Members of NOVAAR, at that time, about LDRS and / or the NAR's position on it ?

If I recall correctly, he advised us to ignore the noise.

If NOVAAR wasn't hosting an event, I don't recall Chris being at the launch. I recall being in Allentown one time and while everyone went to lunch or dinner or something, some guys launched some big motors and a Korey Kline monochopper. It was mind blowing.

I remember some guy named "Warren," he always had some interesting things.

I was away at college when the Blue Ribbon Committee published their findings.
