What weightlessness feels like on Zero-G planes

When I was a pilot in training, we students had to learn spin recovery.  We had to cut the engines back to idle, then execute an uncoordinated turn.  When the airplane would slow to the extent that the wings were not producing lift, the plane would literally fall out of the sky.  When that happened, the plane would go nose down, and spin round and round as it fell.  If we were not using our seat belt or harness we'd float up out of our seat.  Then we'd have to execute the spin recovery procedure.  But for a short time, it was like being weightlessm or in zero gravity.  It was kinda scary, but fun, evoking a laugh when it was done,
