The website

This website has been created with the intention to share the passion for aerospace engineering and aircraft flying. It merges engineering analysis with broader operational aspects.  The use of tedious mathematical derivations is generally avoided to make reading more comfortable. Essential equations are added to the mix if required to enhance understanding. Often it is not the equation itself that should be remembered, but the message it holds.
