Here’s Wikipedia, though you probably know all about it already. The US Navy gun, though it’s the biggest ever, is just a pipsqueak. To get payload into orbit you’ll need one some tens of kilometres long.

Admittedly, they work better on planets with little or no atmosphere. Still, even on Earth the technical challenges are likely to be smaller than for a space elevator.

I not only have evidence of the black TR-3Bs (the triangles), I understand they come in different colors too! Of 1950's technology, here's a picture of a white one, a 1963 TR-3B.

Yes they have images of it on the Navy Eye on the Fleet, though I'm not sure which gallery.

Space Planes aren't realistic for space exploration on a tight budget and for safety for that MATTER.

Look at the two shuttle Disasters.

I suggest people take a look at the comments on the Space.com Site(been on this site for 10 years)

Alot of the Comments are insightful and i will quote a few that are very related to the topic of Space Planes



Also lending Credence to the absurdity of the Idea to have more 'Space Planes' Like the shuttles to satiate your own needs to see the ship as 'Cool'

A Space Capsule is much better for safety and robustness and stability then a Space Plane.


Ultimately, we need something robust enough to handle most situations in local and deep space, be able to be mass-produced, and reach orbit cheaply. THAT will be the ship that gets us off of this planet en mass.


Lets not forget a valid point NASA made: This vehicle is ten times safer than the shuttle was! Not an unimportant consideration for astronauts' families. And another point, is that this vehicle is a modular design. It is a command module, yes similar to the apollo vehicle because that design is proven! Now, the various deep space missions will require different spacecraft designs depending on theire specific goals. So the different mission specific modules are designed and built, but using this vehicle as the reusable command module. Bare in mind it is a deep space command vehicle, not a ground to orbit taxi. Don't condemn it because it happens to look like Apollo. NASA is making the correct descision with this vehicle, and doing it with impecable timing, considering the explosion of private sector space industry about to unfold. Kudos to NASA for being so adaptable in a toxic political environment!

The shuttle was more dangerous than a capsule, but that is not the case for every spaceplane. Shuttle was the most complicated vehicle ever build, it was also very big and with complicated heat shield. Small spaceplanes, like Dream Chaser, are not any less safer than capsules, and have some positives that capsules do not possess, namely lower G-forces during reentry and better maneuverability in atmosphere. They can also land on conventional runway.

Can you provide Evidence that space planes even smaller ones are safer than the Capsules. The Capsules are Proven Safe with the Several Missions Flown During the Lunar(Apollo) Missions. Without a Casualty and this was in the 1960's 1970's!

There was three deaths due to the Apollo Missions; that was due to the testing Process. So You can't really blame them.

You can Blame NASA for the Shuttles though because they are extremely Unsafe For Atmosphere Re-entry and Exit

The Shuttles and ' Space Planes' on The Other Hand. Are Very Unsafe due to their Shape for Atmospheric Re-Entry.

Back to Skylon spaceplane - recent BBC article about Skylon passing key review:

Thread about Skylon on nasaspaceflight.com, with what looks like an actual developer of this spaceplane contributing under nick "Hempsell":

The Shuttle Disaster in 1986 was a media driven disaster. The launch was already delayed twice and that school teacher's class was flown down to watch their teacher go to space live in a media frenzy. It was the only Shuttle launch that went forward in near freezing temperatures, (look it up although one might be skeptical in central Florida at the time but look it up). Many people in Mission Control tried to alert the launch as being hazardous and did actually see the O-ring leak. It was to no avail because we got so complacent in Shuttle and any launch successes as it was like serving meat and potatoes, commonplace. They said we always see these leaks and we will not delay another launch.

It was also human error that minimized the dangers for the other Shuttle reentry chain reactive explosion.

The Shuttles were great birds, the human element made it 'percentage wise', a comparable failure/success proposition but it wasn't the crafts, it was people and media pressure that created the very real deaths of accomplished brave people on board that were killed.

An update for your pleasure....

SKYLON spacecraft's engine passes critical test

November 30, 2012

Reaction Engines Ltd. announced on Wednesday the completion of a critical round of testing of its SABRE engine’s precooler system. The SABRE is a radical type of hybrid jet/rocket engine capable of propelling a spacecraft into orbit or an aircraft in the atmosphere, at a velocity of Mach 5 (3,800 mph, 3,300 knots, 6,115 km/h). It’s intended for Reaction Engines’ SKYLON spacecraft and its airliner derivative, the LAPCAT A2 hypersonic aircraft.


...

SABRE is basically a rocket engine that uses a precooled compressor for part of the ascent. It acts as an air-breathing jet until it reaches Mach 5 and an altitude of 25 kilometers (15.53 mi). By this time, it’s already 20 percent on its way to space. For the other 80 percent, SABRE converts to a pure rocket mode using its onboard store of liquid oxygen instead of air to loft into orbit at a speed of Mach 25 (19,000 mph, 16,500 knots, 30,600 km/h).



Good luck!
