With the SpaceX hopper program in Boca Chica running a little long and the Starship prototype almost ready for engine work, the 200 meter hop next week will be the last. A few dozen welders, plumbers and crane operators aren't enough to keep two operational rocket programs going at once. The tiny cr...Jump to post

Looking at the specs for Stratolaunch and other proposed subsonic launch aircraft I want to ask - is there any significant benefit in lifting your rocket 10km away from the earth and accelerating it to a mere 700-800km/h? A dedicated rocket's first stage passes that altitude and speed within maybe ...Jump to post
Star hopper test successful, apparently. Brush fire at the pad. The brush fire burned for about a mile and a half and stopped 200 feet short of the village. I spent all night on the roof with a bottle of Glenlivet, watching it come. Did firefighters respond or did they keep their distance due to.ha...Jump to post

Knowing the difference between making planes and delivering them isn't that hard.Jump to post
Why did they not try to parachute the capsule in at all? Seems like a waste of money to just let it be destroyed. Capsule was a mockup and had no further use. Capsule was a mockup and the rocket wasn't the one that will launch the real capsule. Compared to SpaceX using a production capsule, avionic...Jump to post
On the morning of 27 June19, an IAF Jaguar aircraft loaded with two additional fuel drop tanks & Carrier Bomb Light Stores (CBLS) pods took off from AFS Ambala for a training mission. Immediately after take off, the aircraft encountered a flock of birds. The bird hit resulted in the failure of ...Jump to post
Whats the charge time between flights on the Evation? That could make for some long turns... The 900kwh battery pack for that plane would weigh about 5 tonnes on a 6.3tonne MTOW aircraft, and it doesn't get any lighter as you use it. Doesn't really add up for me. There is no need to guess figures j...Jump to post

Most drones are still radio controlled, that means there's a radio frequency at which the drone and the controller communicate with each other. If you can track down that frequency and broadcast a strong signal on it that overrules the communication between the drone and the controller, the drone e...Jump to post
As a person of Jewish faith myself, I think that the couple ought to say Mazel Tov and La'haim and be grateful that this abomination of an "airline" decided to ban them for life.

Not sure what to make of this report.

Great news on the ability to carry six AIM-120s internally. This should improve the A2A abilities of the jet and gives some additional flexibility to the weapons loads the jet will deploy with in the future, noting that this is a LM designed and paid for system so almost certainly have to be acquir...Jump to post
The whole thing kinda confuses me. I'd think the US would love to have a partner with an S-400 they could get intelligence from. Which is also why I can't understand Russia selling one to a western (sort of) ally.Jump to post
Nice !! And not very relevant but yet interesting, from now on the world’s largest aircraft has a US flag instead the russian one. Will be weird to see the An-225 as ”just another big plane” but not the biggest. An-225 never was the biggest plane. Stratolaunch is the first plane in 72 years to be b...Jump to post

Although the Spruce Goose is higher and has a bigger wingspan than the An-225, the latter is over 17 meters longer. So, which is bigger?

Shanahan had another go at the F-35 program, this time via Fox News. I’m not sure he is doing himself any favours given the probe that is ongoing into the conduct and possible bias. Trump’s Pentagon chief just criticized Lockheed’s F-35 on Fox News. He worked for Boeing. Acting Defense Secretary Pa...Jump to post

Re: parachutes, I wonder if they could develop a Super Draco-based backup system in case of chute failure. They already abandoned propulsive landings for Dragon (I wonder if they'll ever regret that), but it probably wouldn't be too hard for SpaceX to develop a last-resort retro-boosted splashdown ...Jump to post
Makes me feel old. The last kit plane I was involved with was a VariEze put out by some guy named Burt Rutan, who showed me around the shop in Mojave. Could have used some student help. It wasn't exactly an "Assemble in three weekends" project.Jump to post
What’s different about the rocket engines SpaceX uses compared to those in the past. Lots and not much? The Merlin is still a Kerosene-Liquid Oxygen (Keralox) engine as tons have been. Even the F1 in the Saturn V was a Keralox engine. The biggest difference is the effort SpaceX has put in to bringi...Jump to post
Partially, the engines will have more sound absorbing material. Quite a bit has been learned from the business jet aspect. The GV (early gulfstream V) had the area buy the engines (couches) so loud, they really weren't usable. Same with the early global express. Then bombardier upped the insulation...Jump to post

Then why, after many years of development and billions spent, did USAF not specify a boom pod? Surely USAF knows what it needs and had sufficient clout to get exactly that.

I love how ironic this is for the Canadian Government. Flop back and forth and end up having to pay more to support a program the Liberal Government campaigned they would leave. Then run an open competition with signs pointing to the F-35 being selected in 2021, especially if the unit flyaway cost ...Jump to post
