Catching own airball??

[B-Real1]

I have always assumed that catching your own "airball" shot was a travelling violation. At least it was always called on the playground that way. Last week, in a rec league game, that situation happened, and one ref(the rookie of the crew) called travelling. But then one of the other refs said that as long as the player was attempting a shot, he was able to catch it, without it touching the rim, backboard or other player. I asked the ref after the game if that was a new rule and he said it wasn't. Did he make the correct call? NBA rules claim it is travelling. Do the high school rules differ in this case? Also, is there anywhere on the net to actually read the OFFICIAL HIGH SCHOOL BASKETBALL RULEBOOK? I've searched high and low to no avail. This situation occurred again last night on the playground and I almost got laughed off the court when I tried to claim it wasn't travelling.
