Agreed. This guy regularly ferries GA aircraft across the Atlantic. In the video below, he’s taking off at 30% over max gross for a non-stop Bangor Maine to Tenerife, Canary Islands flight in a Cessna Caravan. There’s another guy who recently ferried a new C172 from California to Hawaii (supposedly he’s done it several times).
And one of our forum colleagues here recently flew a simulated Wilga across the pond from Germany to the USA.
