That's right! Since -as you already said- there are various
aspects of "free". Therefore, there is no field of application
of term 'reverse engineering' especially under the licenses
'Free Libre Source Code' and 'Public Domain Source Code',
since there is nothing there to disassembly it.

Moreover, under these licenses, ethics impose to give in return
at least as much as you get. This is especially holds in VEMSA3D
case, in which we get the Source Code included in J.H.Richmond's
report:

"Computer program for thin-wire structures in a homogeneous
conducting medium"

or just

"Computer program for thin-wire structures"

from NASA Technical Reports Server at:
http://ntrs.nasa.gov/search.jsp

Well, this source code has 1,044 lines of code, in 16 routines:

(1,044 = 100 + 61 + 158 + 36 + 9 + 98 + 120 + 104 + 40 + 64 +
+ 45 + 22 + 22 + 40 + 87 + 38)

and in return, we give for now:

* only 3 comment lines less than *

those exist among these 1,044 lines -as one can easily find
them in SGANT routine, at page 22, of the aforementioned
report.
