In the USA, can one depart VFR and then change to IFR and back again?
Here in the UK this is done all the time. But one isn't supposed to do
it in e.g. France because *any* IFR requires an IFR flight plan, and
an IFR clearance.

The last bit should be OK because one can cancel IFR, AFAIK.

Europe's system is not flexible, we are.
