OK, WWW, that is all well put and makes some good points, whether or not any of us choose to agree with them. I suspect that if you'd posted like that in the first place there wouldn't have been so many people thinking you were out of order.
On sending a student off solo with CBs around...
As you say, it could have been an isolated one which the instructor was sensibly pointing out. The wx could then have got worse, unexpectedly and unforecast. It's possible.
On the other hand...
I have heard of one flying school owner (no longer around, I believe), who used to INSIST on having his aircraft flying all the time if humanly possible. I've heard stories - and I personally trust their source - of instructors being told by him to send students out in unsuitable weather, on pain of dismissal. I'd accept the dismissal...but I'm not thousands of pounds in debt with a family, and some instructors are. I heard of one solo student who got lost in low cloud and rain, and found and led back by this owner, and according to the person who told me, it was a miracle the person was found.
True or false? I don't know; I wasn't around at the time. I'm spreading rumours - but note this is the Professional Pilots RUMOUR Network, so I can. The point is, it COULD happen. ANYONE can start and run a flying school. So did that happen in Phoenix's case? Who knows? Students need to be careful, and perhaps WWW's cynicism is sensible.
Just to get things in balance, I've been around a bit and the majority of flying school owners and instructors I've met are caring, hardworking, and doing their best at a difficult job. But not all!!!!
