An important message to those sending email to 
Aircraft Design Research LLC or Daniel P. Raymer:

If you use a spam blocking filter or a spam blocking service such as Earthlink’s, I don’t blame you a bit! I get over 300 spams a day since my email address is on this website and the spammers, may they rot you-know-where, are now smart enough to get around the little tricks I use to hide it. 

However, some spam filters and services require the person sending an email to log on to a website and answer some questions before the message is sent to the intended recipient. This takes time; about 5-10 minutes in my experience. If you send me an email from which you’d like a response, don’t expect me to take this time in addition to the time it takes me to answer your letter! I get 5-10 such requests a day and always answer them myself. 

So, if you have a spam filter and send me an email from which you’d like a response, PLEASE – take the needed steps yourself to put @ aircraftdesign.com on the “not-a-spammer” list!

BTW, I love spam. The real stuff, not the email junk. I slice it thin and boil it for 5 minutes to remove some of the salt, sugar, and fat. Then I pan-fry it and stir in two eggs. Yummy! (Caution – regular spam contains pork which is against certain dietary restrictions. There are pork-free versions.)
