I believe mark is using this plane and I have no idea what it is
It says it right there. Avro Canada VZ-9 Avrocar. :)
They’re testing a new aircraft, this is just to hide it’s real name.
That’s probably the MD-11 or DC-10, they’re testing it!
Not to speculate… But could that potentially be a beautiful Alitalia MD-11!?!
No but it is a new aircraft/livery that they are flying with and testing out!
