July 2001 (evening) launch report (7/7/2001)

It was on short notice; It was a beautiful summer evening; It was a small (but loyal) group of rocketeers.  (You can kick yourself now for missing it!)

On Saturday evening, July 7, a few stalwart MASA members gathered at the sod farm in Blaine.  This special evening launch had been called on 24 hours notice.  Launching was limited to 1 lb rockets, but that didn't keep the numbers down with 41 flights recorded.

This launch was BYOLS (Bring Your Own Launch System).  It used a type of "misfire alley" range setup with a flight card being filled out for each flight.

A few of the flights:

 Alan Estenson's "Big Bad Voodoo Daddy" lawn-darted into the mud on a D12-3 flight.  Seems someone forgot to plug the unused 18mm cluster tubes...  Later Alan flew the BBVD again on a D12-5 and cluster of two C6-0's.  All three motors lit and the rocket was stable.  Unfortunately, the C6-0's blew out the bulkheads in their motor mount tubes and caused an early ejection.  Kent Peterson had some lack-of-chute-appearing problems in his Big Bertha, but overcame them.  Kent also had an impressive flight of his Super Big Bertha on a D12-3.  Glen Overby had a long walk to retrieve his Aerobee 150A launched on a D12-5.  Dave Fergus and Tim Bush both flew Mercury Redstones.  Dave had a shy parachute on the booster, but there wasn't any damage.  Tim also flew his down-scaled Sub-Orbital Transport on an A10-3t.

Glen Overby successfully staged his D9C on a C6-0 to C6-7, but Dave Fergus wasn't as fortunate when he flew his Comanche-3 on B6-0 to B6-6. Alan and Tim both had strange flights due to odd nozzle erosion causing thrust vectoring.  Tim Bush's Tartar was dramatically unstable on a F20-7, and Beldar lost his head (but it was found) when flown on two C6-5's.

Alan Estenson successfully flew his LOC Onyx on a F20.  Dave Fergus flew his Cosmodrome Nike Smoke on a F40, but it (and his RMS casing) was lost to the trees to the east.  It was joining the upper portion of Alan Estenson's "Mimi" which had drifted there earlier after an ejection separation.   Later, they were joined by Glen Overby's Nike-ASP, flown on a F24-4, as Glen declared that the "Rocket-Eating forest prefers Nike's" (and RMS casings).  Alan tried to send his "Super Dubro 511" to join them by relabeling it "Nike Wannabe" with black marker and stuffing a G35 in it.  However, a shy streamer resulted in a ballistic recovery into the muddy field.
