But if you could fly, falling off of height would no longer be any risk, thus no more reason to fear!
I wonder if this will be the US theme too? I'd struggle to pick one, since thematically I like invisibility better, but flight would be way more practical in my every-day life. Hmm...
Much better theme than the first two, either way.
Well there's a lot of things to consider with flight other than just general fear of heights:
a) How fast do you fly? Flying at 4 mph sounds pretty lame.
b) If you do fly super fast, does the air resistance fuck up your face, or do you need a helmet?
c) Can you fly super high without worrying about changes in air pressure?
d) How many bugs will fly into your face? What happens if you hit a bird?
e) How easy is it to turn, slow down, etc? Momentum would be a bitch if you had to go from mach 1 to stopping on a dime.
f) Does it tire you out? What if flying was as exhausting as running?
g) Are you guaranteed to look cool while flying?
See, lots of things to consider. Invisibility is much simpler.
a) Do you have to take off your clothes?
b) How long does it last?
