Default ____________ NASA seems close to adopt MY "underside-LAS" ... :) :) :)

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 document:

http://ntrs.nasa.gov/archive/nasa/ca...2007018905.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 FARING 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 (like happen with rockets)

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" ???
