Useful Research Websites

What follows here is a list of freely accessible websites, that can help you find the correct data for your photo.
However, it is important to understand that no website is perfect, and errors are often copied from one website to another. It is a sad fact that even the official civil aircraft registers of many countries are full of mistakes and incorrectly interpreted data.
Our database editors make every attempt to keep AirHistory.net free of such errors, but even here errors will occur from time to time.
You will sometimes note that the information given in our photo captions does not match the data you can find on the internet. This can be a mistake on our part, in which case we would like to hear from you, but it is possible that most internet sources are wrong.
Our Identity Myths page highlights and explains examples of such cases.
