<br />A. demonstration of how it works should be arranged (if anyone <br />is still interested in purchasing one of these things). First, try <br />to obtain various sized hailstones after a Bevere storm and freeze <br />them. Next, set up the sound gun 4 - 5 miles away from a tall <br />structure with an unrestricted view of it frOm such a distance...s <br />grain elevator would be O.K. while at the top of the structure, <br />put the hail into something like an ice tray and have a pole or <br />board already rigged so that it can extend out several feet into <br />the open and which would hold the tray at such an angle that.the <br />hailstones wouldn't fallout of the it. Face it toward the sound <br />gun and make sure there is something below the tray to catch any <br />broken up hailstone particles, if it should happen. When the sound <br />gun ia fired/any effect on the hailstone ought to be seen about 20 <br />-.25 seconds later. !f th~ hail breaks up into many pieces,. YOll'd <br />better take them up on their $70,000 machine. And for myself, I'll <br />be tempted to switch into weather modification by sound gun. <br /> <br />~=~=~~~=~~=~~~~~~~~=:~=~~~~:~~~==~==~=~~==~=~~===~====~~~c=z~~~~~ <br /> <br />OPSRA~IONS (All times given are CDT)l <br /> <br />~ULY 20th - OPE~TIOBaL DAY #3~: A cold front moved through the <br />region the previous day slowing down in its southerly movelllent <br />while passing thro~gh Southwest Kansas. six observation flights had <br />been launched the previous afternoon and evening. Storms continued <br />to be generated over the frontal boundary as we passed midnight. <br /> <br />At 12105 a.m. some storms began to exhibit aevere tendencies <br />and two cloud base aircraft were scrambled for storm development <br />near Coolidge. The other two base seeders were scrambled at 12:31 <br />a.m. and 1:40 a.m. Seeding began at 12:52 a.m. near Coolidge anq <br />was joined in seeding by a second plane at 1:16 p.m. The third <br />aircraft began seeding a separate storm in Northwestern Hamilton <br />County at ll22 a.m. As storms continued to develop in and around <br />the southwestern part of the target area, an arc-shaped line of <br />~torms evolved which included the seeded storms; it lay on a line <br />running from near Coolidge to Lydia, in southern Wichita County, to <br />C1marron and on to BUCklin. The best ~reas for seeding were in <br />western. andnorthwesternHamiltonjcentra:J. and weatern Greeley and <br />some in northern Scott County. All seeding ended by 3: 09 a.m. Some <br />rain stimulation was performed within portions of the line. Total <br />flight time was 10.9 hours. <br /> <br />~ j).~~ <br /> <br />Curtis D.
