For my American readers, I would like to point you to a new website I discovered a while ago called Ask A CFI.
The owner is a flight instructor that encourages it’s readers to ask him questions. In turn he will post the answer on his website. Recently he commented on TCAS and an incident that happened in the US where an F-16 pilot intercepted two aircraft without any reason.
On a different note, there have been some changes in the works behind the scenes for this website. Upgrades, redesigns, etc..
Stay tuned for more information.
