Gordy, here you go.

This is my pencil drawing of the lower transition, sized as you indicated for BT-60 core. I used your booster cone drawing to line it all up.

Sorry it took so long.

Not sure but the pics I have make it look shorter.

You may be right. I can't tell for sure.

Same angle as the booster cones but shorter.

I believe the ID of a BT-70 is 2.175" so the shoulder should be 2.17 not 2.18. We specify about 2.165 on ours.

The body tube chart I use shows 2.18" but actually I fit the shoulder to a section of BT-70.

I just use the dimension for the drawing.

Gordy, you may be right about the first transition being slightly shorter than I drew it but your most recent drawing needs a 1/4" x 1.64 segment and then transition to the next size. The core and the boosters are identical; as long as the booster noses have this straight section (and they should), the core needs the same straight section before transitioning to the Series 18 tubing.

OK, but it will have to wait until AFTER I have turkey!

I don't believe it. They really launched it!

Now, I need to order enough balsa parts from Sandman to help pay for his Christmas . . . .

WONDERFUL!!!

This is about the "spacey-est" December since Apollo 8, or Apollo 17...

Congrats to the EFT-1 team and now to the Angara team... and India as well...

Later! OL JR

The Angara A5 launch makes Russia's recently announced national space station and manned lunar exploration plans sound more realistic. To reach the Moon, Angara could be used in EOR (Earth Orbit Rendezvous) mode, as NASA had wanted to do with Apollo, because a larger Moonship could have been used. (Cost and time constraints, plus their lack of rendezvous/docking/EVA experience in the early 1960s, caused them to opt for the simpler LOR--Lunar Orbit Rendezvous--plan, which involved landing the minimum amount of equipment on the Moon.) Also:

If Russia arranged to launch Angara from Kourou, as they now do with the Soyuz launch vehicle, it could boost even heavier payloads into LEO, GTO, GSO, and to the Moon. Manned Venus and/or Mars flyby missions (which could encounter *both* planets if launch dates were chosen carefully), manned planetary orbiter missions (including unmanned, real-time driven Mars rovers and manned Phobos & Deimos landings) could also be conducted in EOR mode using Angara. Manned Mars landing missions are also a possibility, although a larger number of Angara launches (to ferry the interplanetary spaceship and the MEM into Earth orbit, possibly with their propellants being launched separately and loaded aboard in orbit) would probably be necessary. But having the problem of "*HOW* do we do this?" is vastly preferable to the problem of *CAN* we do this?"

I don't know why Randall Munroe omitted the Angara 5, but it's about 55 horses.
