Even the most experienced pilots can get into trouble when they lose situation awareness (SA). It will rarely be the tree in front of you that eats your bird (don't ask how I know!). I soloed in 15 hours when getting my private ticket, but still had and have a lot to learn. Same with flying these birds. Like the others have said there are so many things that you really need to be aware of and keep track of in order to fly safely. By the time you have run through a couple of batteries, you should have the basic skills to fly a phantom. But even after 100's of hours, it only takes one mental lapse to wipe you out! Like the saying goes "it only takes one o'sh@&@t to wipe out a hundred ataboys!"
