Reading Ewalds full statement I believe he penned it.
The grammar and syntax are a giveaway.
The revealing paragraph is this.
On the following expeditions I took over the tasks of supporting Tracey Curtis-Taylor with all the flight planning and logistics. Besides I am taking care of the technical needs of this airplane, the chase plane, supporting the ground handling, filming and ordering the drinks for the crews in the evenings.
I love that last line.
Like a chauffeur sitting up front all day he has to "order the drinks for the crews in the evenings" (sic)
Please read the above with an Austrian accent
Reminds me of the TCT quote to Sam Rutherford.
"Sam...What can be more important than getting my luggage to the hotel?"
