This little scene was a spontaneous idea I got while taking some photos of origami ponies in different poses (lying, standing, walking, running and flying).  
For Twilight’s flying posture I had picked one which implied a steep (possibly unintended) dive and remembering her flying problems after her alicornization I thought of a scene depicting her flying training. Fluttershy and Rainbow Dash soar along to catch her (and will most likely succeed), but in case they don’t AJ and Rarity too stand ready to catch her (with hooves and / or magic) while Pinkie Pie has pillows ready for this situation because… because of course she does She seems to have borrowed said pillows from the Hooves.
