Hi everyone. This weekend i had my first really long flight with a single seater. Together with an other colleague in his single seater we went off and at one point needed to cross the border to France from Switzerland. The problem is that i did not had a flight plan. I somehow got it wrong and tought i do not need one. But after landing some other colleagues told me otherwise.

Whats your guess, should i wait for a letter or contang the french authority DGAC? What would you do?

Ps: sqwak was 7000 and all the time on and i did not enter any controlled or restricted airspaces.
