So now I stand in this device and launch myself into the wild blue yonder with
a head first vertical takeoff - exactly how do I land it again?

I've made that point on posts to Scientific American and Avweb. Watch the
animation, it magically comes to a stop in mid air, rotates to vertical and
descends.
Personally, I think they didn't name it after the bird, but rather for what
they were doing when they dreamed up this fantasy.

Roger:
I meant to reply to you on this subject, but forgot. I have and Allegro 2000
with a Rotax 912UL engine (300 hours). The four engine mount bolts on my
plane were torqued and safety wired when I mounted the engine. The safety
wire is still in place and there are no signs that the bolts have loosened.
Do you feel that I should cut the safety wire and check the torque, then
re-safety wire?

Hi Hugh,
You should not have to do this if these were torqued to 30 ft/lbs at the beginning
and the safety wire should keep these from loosening. If they are not safety
wired for any of the other guys who read this and have that type of engine
ring mount they should be torque checked every 100 hrs or annual which ever comes
first. These do come loose and I have found many that are 1-4 turns loose
and this will let the engine sag and move around under different throttle settings.
If you get at least 3 bolts loose you can pick up the plane out by the prop
and the engine will wiggle. This situation will start to trash the threads
in the bolt holes.
