Two relatively short hops (roughly 135nm and then 95nm). The first leg we know she did solo as there is video of her leaving Farnborough. Did she wait at Merville to pick up Ewald before flying on to Charleville?
To be fair to TCT flying across the Channel solo in a vintage open cockpit stick and rudder plane takes a bit bottle, every time I coast out at Weymouth making for Cherbourg my arse is all puckered up for the entire crossing and that's with a back-up AI and an instrument ticket.
