Yup & the risk to a human were it to go wrong. However with a drone,
mistakes can be made & all that's lost is some money.

I reckon drones will give a whole new impetus to new aerospace designs
which have been basically stuck with the WW2 developments i.e. all the fun
stuff was developed/tried in the late 40'es early 50'es & since
then.....stasis.
