NASA seems close to adopt MY "underside-LAS" ...

in an effort to increase the Orion's SAFETY and REDUCE its (now oversized) mass (of about 1000 lbs.) NASA seems close to adopt an "Alternate Launch Abort System" (ALAS) as explained in this NASA document:

http://ntrs.nasa.gov/archive/nasa/casi. … 018905.pdf

the ALAS works EXACTLY like MY (February 10, 2007) "underside-LAS" published FIVE months ago in this article:

http://www.gaetanomarano.it/articles/020newLAS.html

as you can see from the pictures in the NASA document, the ALAS has a big FAIRING that forces the abort motor's thrust from the top of the LAS to the bottom of the Orion's Service Module, so, in both (ALAS and underside-LAS) systems, the Orion capsule (on abort) is NOT "dragged" from the top, but "pushed" from the bottom

the ALAS has two different designs, one with the LAS' flux canalized on the external side of the fairing (ALAS-1) and one with the flux canalized on the internal side of the fairing (ALAS-2 and ALAS-3)

unfortunately, the NASA design (in the ALAS-2 and ALAS-3 versions) looks VERY DANGEROUS since (on abort) the LAS motor's (very hot and powerful) thurst flux "travels" between the fairing and the capsule with the astronauts!!!!!!

also, the ALAS seems NOT able to reduce the Orion's weight (as claimed) since it needs a big (and heavy) fairing and nearly TWICE the LAS motor's power/mass/dimensions/price to push (on abort) the GIANT Orion+LAS+fairing+Service Module mass!!!

so... why NASA doesn't adopt MY (ways simpler, safer, cheaper and lighter) "underside-LAS" ???
