You can spend a WHOLE LOT of time viewing the AF Museum on-line.
When you click on the "Start" a map of the museum will dominate the r/h side of the screen. The map can be closed by clicking on it but there will allways be a "Map" tab in the upper r/h corner should you get lost.
Move your cursor around the small dots (photo locations) in each hall. Start from #1 which is outside.
In each image as you pan there will be one or more `virtual blue arrows' on the floor. As you mouse over them a small caption and a number will appear. Click on the highest numbered arrow in the image to advance to the next image or you can go around in circles.
Some images have video inserts. Look for a "Play" arrow on the wall.
Good for at least an hour, maybe more depending on how long you dwell.
The only thing missing is a description of the aircraft. There was no audio in spite of the speaker image.
