I don’t disagree with any of that as a fundamental principle of flying safely. It is largely reflected in the training that CSIPs provide and is also part of the CPPPs organised by COPA.
The point about it not being the responsibility of people on the ground to get out of the way is quite right, but it applies equally to an aircraft gliding in at or above its stall speed. The accident link I posted, and a similar recent tragedy on a beach in Spain, are sad illustrations of the consequences of an otherwise apparently competent pilot getting that aspect wrong (I’m not sure, but think I recall reading that in the Spanish incident there may have been an instructor in the aircraft?).
They obviously didn’t kill those people deliberately, which means that they lost control at a critical moment. History suggests that in both cases, had CAPS been available (sadly it wasn’t!) there would likely have been a better outcome if that option could have been taken.
