Canadians Mowat, Donovan, Hood and crew with the help of a bottle of gin, snatched a V2 off the train, disguised it as a German mini sub and hauled it back to Canada right under the Brits and American nose. So after looking at all the V2 paint jobs, realizing that the Canadian rocket didn't fly...

We've been docking in space for decades. We know how to send landers/rovers ahead and put them on a foreign surface. So why do we insist on building one huge rocket to take everything to the moon in one trip instead of staging items enroute or landing as separate modules? The ISS wasn't...

something you threw together without concern for spirals, fillets, or colors just so you could fly the bejeezus out of it?

Does anybody know what the colors may have been on the V2 that was put on display in DC just after the war? I'm guessing silver or bare metal and red or black on the fins and upper. Every pic I find is referenced on the V2 Resource site and is a black and white with no description. TIA

school grounds. Less than 500ft to either side, residential areas on three sides and automated sprinkler system! For students to get their go at either mode, I have to keep the rockets in sight and not set the neighborhood on fire.

😁Got to launch my rear eject, Big Daddy today! Almost a year of waiting between burn bans/fire danger warnings, high winds, life, and work. Lift off great, climb out great to about 50ft, weather cocked, and warp speed in to the hill side 150yds away! Lots of ooooohs and aaaaahs changed to oh...

Have any of you that use flat elastic in your shock cords ever loosely stitched in a piece of colored thread to see just how far the elastic stretched during chute deployment? I've seen visual strain indicators on heavy kevlar lifting harnesses and I'm trying to figure out just how much elastic...

Pretty certain the civilian sector will have to make an obligation for long term habitation of the lunar surface before the winds of politics will. https://www.cnn.com/2020/04/30/tech/spacex-blue-origin-nasa-human-lunar-lander-scn/index.html

Given that we should've already been there three decades ago, it honestly feels like the civilian sector will be the impetus for any long term occupancy on the moon. Seems like a good place to repurpose the ISS...

Not a minute went by and I started debating 18mm or 24mm. But its a classic kit and flies as is but I might want to use a D engine or....... My Semroc Mars Lander may take a little longer to build ;)

Just had to replace my garage door opener. The old rail is about beefy aluminum I beam 8'6", three piece, and slotted. The slot opening is 3/8 wide and 1/8 thick T slot. The more I look at this thing the more I think that its begging to be used as a launcher with flyaway rail guides. Maybe a...

6599mph ain't exactly collecting dust!

and the weight of the rocket left to hang out over the outer two thirds? Inquiring minds want to know...

Where does one begin...;)

but was wondering if anyone knew the weight in grams of a 4x6in or 6x8in piece of either one?

If you were going to build a Leviathan off a Big Daddy kit and extra body tube, and you were thinking about flexible motor possibilities, and you were thinking about staging/clusters using a previously cut-down Big Daddy lower body; where would you go with that?

Was eyeballing a Minuteman III on static display at the local air patch yesterday and noticed the shape of the nose cone and transitions. That made me think back to the rules of pressure in my Aerodynamics course and then the hull of a boat and how chines and strakes are used to break surface...

Or in to the black hole! School district announced a 1k student count decrease and a subsequent $5m funding loss. Programs and staff cuts on the table. All the aerospace initiatives we've been preparing for, maker space, materials, speakers, and club schedule just got put on hold. Grrrrrr Lost...

Is there an effective ratio to the body where they no longer are effective?

Just stumbled over this today https://www.bbc.com/future/story/20150824-how-a-nazi-rocket-could-have-put-a-briton-in-space
