Sky Racing?

These two caught me by surprise! I was busy snapping tiny flowers and grasseeds, camera set on micro, when I heard them coming, but I was not tóó excited I thought it was just another small plane passing, like só many times every day! Geezz what a struggle to change settings, get them in focus and shoot!! This one, although not tóó great, is the best I could do!

LATE EDIT:

I found this on the web about the 'new' one in the foreground. It is an 'Aero L-39C Albatros'.
