close call !

went over to Boxer's lake to see if I could take some photos of the birds flying  but there was very little going on. I then spotted these two planes approaching from opposite directions. They crossed very close to each other over the middle of the lake. I assumed they were some sort of team practising a routine but looking them up they don't seem to be . I wonder if they just didn't spot the  other plane until they were virtually on top of each other.
