It is possible the guys working on it also had other duties.

Note that there were likely not as many people working on the project as would
be working at a drone manufacturer designing their next product.

And this drone had to be super reliable, and it had to work in the atmosphere of
Mars, which, as the article noted, is a *lot* less dense than that of Earth.
(The article said 100x; I thought it was more than that.)
