according to her webpage in 2015
"The Cape Town to Goodwood flight took two months to complete with 38 stops. Tracey was supported by a second aircraft; a Cessna Caravan provided by Phoenix Aviation of Nairobi, which carried a logistics manager, an engineer and a four-man film crew."
so the engineer was carried in the support plane. If he'd have stayed there there probably wouldn't have been quite so much kerfuffle?
