I thought it was a diet with too many beans. 
Gaseous Thrust
I vaguely remember.seeing episodes in syndication. The Flying Nun wasn’t a show I watched regularly.
Sally’s show Gidget ran one season.
The Flying Nun did better with three seasons.
Hang onto your habits — Sister Sixto, who was just a tad older than Bertrille, left the convent and went to work for Karen Walker!
I think they remade that as “True Blood.”

As I recall, it was offered to her some time after Gidget was cancelled. ABC executives realized they had made a mistake when there was an upsurge of fan support in the summer of 1966.
Gidget’s one season had 32 episodes at least
That and the screams of children.
Huh, and I had always just assumed it was miraculous.
Several times when asked, the Flying Nun “explained” her flight this way: “When lift plus thrust is greater than load plus drag, anything can fly.”
You put a big enough engine on it, and a washing machine can fly.
Despite what Sister B said, I think a wizard I mean God did it.
I think there was also something about the specific kinds of wind found in that part of Puerto Rico.
That was how I remember it, and Wikipedia agrees:
Back then it was called Chroma Key. You will still hear people talking about “keying out” the background. Though blue was more common than green, as blue is not present in fleshtones.
How did the Flying Nun fly?
Not with a bang, but with a wimple.
Force of habit.
She was Nun of the Above.
Nuns were sitting on starches that can make common linen stronger that modern carbon fiber!
This was a conspiracy by Big Starch 
to showcase their goods, but not invest in the good works of their most successful (and unpaid) publicity creator!
Okay, I have to state “Well done!” for this one. Wish I had thought of it. 
My Mother the Car was apparently a suspension too far.
It’s all nunsense to me.
