I recently had the pleasure of doing an article on “Modular Escape Cabinsâ€

in my thread about this concept ( http://spacefellowship.com/Forum/viewtopic.php?t=8616 ) I've posted these questions to Robert Talmage's claims:

"The unique aspect of the TAAS escape cabin over the F-111 and other cabin ejection systems is the attachment technique and gliding capability."

in other words, you haven't invented the (decades old) "ejectable crew cabin" but just added new junctions (explosive bolts?) and wings to allow the ejected cabin to glide and land like and airplane... it's correct?

or, if it's not, can you explain me/us which exact part of an ejectable cabin you've changed, then patented?

"The proposed project to demonstrate the escape cabin involves modifying an old Learjet."

it seems too expensive to destroy a full scale airplane to test the ejectable cabin rather than just test it on scale models

"...operate the modified vehicle as a sub-orbital space flight..."

the ejectable cabin could help if the spaceplane goes to a bad trajectory, but I doubt it could save the crew if the (pretty close to the cabin and ery much bigger than in a common airplane) propellents tanks will explode (since the explosion is several times faster than the fastest possible cabin ejection)

however, where is the advantages of wings over the parachutes (I suggest for a Shuttle's ejectable crew cabin) or the paraglider proposed (but never used) in '60s for the Gemini (to land them on common runways rather than on sea)

the crew cabin wings are very much bigger and heavier than a simple parachute


so, from his new text, it seems he says that he haven't patended the (already existing) "escape cabin" but only the "plug-in devices" that join the escape cabin with the spaceplanes' body... it's correct?

the winged escape crew cabin looks very much like the (VERY expensive and deleted) HL-20 project: http://www.astronautix.com/craft/hl20.htm

and the X-38 project: http://en.wikipedia.org/wiki/NASA_X-38

that was designed to glide (with wings) and land (with parachutes) in the same way:

Guys,

Be sure to listen to The Space Show this week!

There will be a follow on from this article, it should be a great listen!

Sunday, January 11, 2009, 12-1:30 PM PST (20-21:30 GMT)
Robert Talmage comes to the show to discuss his innovative escape vehicle program for aircraft and rockets/space vehicles. Robert Talmage is president and founder of TAAS Company, a small design and contracting company. Robert earned a BSAE from the University of Georgia. While attending school, he also received his private pilot license. In 1986, Robert designed a hypersonic rocket transport. The concept was published in Popular Mechanics, Design News, Omni, L-5 News and later presented the design at Clayton College, Georgia during the Space Day Symposium. One aspect of the concept was to provide a first stage capability using a tow plane. This feature was adopted by Kelly Space and Technology and successfully demonstrated by NASA in 2000. Recognizing the lack of a suitable escape system for future space planes and military flight crews, TAAS began work on the “Aircraft Escape Cabinâ€
