Total impulse for the day = A hefty 8280.2 Newton-Seconds, equivalent to a nice "M" motor. WHOA!
CATO 5 Launch Report
July 28, 1998
Durham

(photo #3) -Jay's NCR SA-14 Archer cruises skyward on a G35-4W Econojet.
(photo #4) - The Archer floats down from over 600 feet and nearly re-inserts itself on the mantis launcher it just came from! To the right, awaiting launch, are Mark 'Connell's Mountainside Hobbies ADR 4.0, Sandy Alonzo's 2.6" tube fin rocket, and Paul Welling's PML 3" AMRAAM.
(photo #5) - Sandy's ADR 4.0 flings itself into the sky on an H180 White Lightning reload. This was the 2nd flight of the day for this rocket/motor combo. The first flight gave Sandy his level 1 certification (CONGRAT's!). This flight suffered a separation.
(photo #6) - Jay's highly modified Public Enemy 1/4 scale Patriot darts upward and to the north on an H238-6T reload. This was the only airstart of the day, and in fact the only complex composite engine flight of the day.If all goes well, a Transolve T2 timer should be triggered by the sudden acceleration and zap a couple of Fire-in-the-Hole tungsten igniters at 0.5 seconds after liftoff. These should ignite a pair of F12-3J 24/40 reloads.
(photo #7) -. ..long pregnant pause...YES! We have 2 black smoke trails! It took nearly 3 seconds for the BlackJack engines to come up to pressure. Ejection from the H238-6T occurred before the F12-3Js were done with their 3.5 second thrust (because of their unexpectedly long pressurization time), but the rocket's velocity was relatively low and she held together just fine.
(photo #8) - Mesmerized by the spectacle, the crowd gazes in awe at the triumphant return of "Pat" from her seventh and most recent airstart. The white chute is a 56" Army surplus flair parachute. (In case you haven't guessed, I kinda like flying this rocket).
(photo #9) - Jay flew his vintage Mercury Redstone on a C6-3 in honor of Alan B. Shepard Jr., America's first astronaut and lunar golfer, who passed away earlier in the week. God speed Alan Shepard.

A review of the flight cards reveals:
We had 23 rocketeers, nine of which flew at least
one high power bird.
We had 114 flights, representing 72 different rockets
burning a total of 135 engines (1/2A through J).
Most rockets flown: Sandy Alonzo (15), followed
by George Boulas (12), Pete Tolx (11), and Jeff Thomas (10).
Most flights with a single rocket: tie between Alysia Hogan's Ninja and Sandy Alonzo's Tri-F-0 (7 flights each).
Paul Ludwig flew his Estes Bullpup four more times on C engines, for a total of 42 flights for this lucky rocket!
Most newton-seconds burned: Rob Larson (1516.9) barely edged out Paul Welling (1504.6), followed by Sandy Alonzo (591.2),
Dave Sousa (508.5), Bill Piedra (483), Jay Calvert (481.2), Mark O'Connell (461.4), Paul Schoen (399.1), Pete Tolx (377), and Kevin Toner (333.6).
Black powder clusters and multistage rockets were flown by Elyse Nastahowski, Bill Piedra, Jeff Thomas, and Pete Tolx. Bill flew an incredible 2-stage cluster rocket, with 3 D12-0s in the booster
and 3 D12-7s in the sustainer. Worked perfectly!
Gliders were flown by George Boulas and Pete Tolx.
There were THREE level 1 certifications: Mark
O'Connell with a Mountainside ADR4.0 on an H180 reload, Paul Schoen with an LOC IV on an H123 reload, and Kevin Toner with a scratch built Fat Boy upscale on an I161 reload. Congratulations gentlemen!
There was also a level 2 certification: Rob Larson flew a beautiful upscale Big Bertha on a J350 reload. Way to go Rob!
Paul Welling also burned a J350-6W in his LOC Bruiser
(which he certified on at RATS VII).
OUCH! We had a near miss Sunday. Rob Larson's 5.5" upscale mosquito boosted straight up on an I211, then popped the nose cone but failed to eject the parachute. It came down fins first, and very fast. The LCO blasted the warning horn and people got out of the way, but the rocket hit hard between two parked vehicles. Could have been MUCH worse. Everyone please keep your eyes and ears open and your thinking caps on during the launches.Safety first!
CATO VI is scheduled for Sunday August 30 at the Durham site.
