In addition to offering PAF, the Family History Library runs the web site www.familysearch.org. The library is in the process of digitizing their over 2 million microfilms and making the data available on-line and for free. There's a long way to go, but it's worth looking at.
If you decide to use PAF, the add-on program PAF Companion produces nicer looking reports of your data that the built-in PAF functions, and the cost is quite low. And since PAF will export a gedcom (a genealogy data transfer protocol that all genealogy database programs recognize), if you decide later to try a different program, you can easily move your data.
Different approaches are used depending upon the frequency of the radar that you're going up against, and the tactics involved in the defense ring.
First detection is usually handled by a long wavelength radar and after detection the target is handed off to a tracking radar, which uses a shorter wavelength, and finally to a targeting radar that uses the shortest wavelength.
One tactic is to avoid that first radar, then you're never handed off to the next layer. The Horton could probably get past the coastal radars, and after that it might be able to approach its target unhindered.
The fact that there was a carbon layer in the wind leading edge (a primitive form of dielectric RAM) indicates that radar reduction was being considered. The Nazis also coated the periscopes of their submarines to reduce the signature after they learned that the British had radar on their search airplanes.
I'm an engineer with a large aerospace firm. All our major programs are in Fortran and have to be used, modified, and maintained.
I remember a few years ago we hired a new grad from MIT; she had studied Basic, Pascal, and C; so of course we had to teach her Fortran so she could do her work.
The engineering world is heavily dependant upon Fortran, and to not know it puts you at a huge disadvantage.
