> but how hard will it be to just fly a drone there with some kind of projectile?

It's a massive long metal tube full of extremely flammable things...what seems more likely: drone with projectile entering a highly restricted piece of airspace, or as rockets are want to do, it blew up by itself.

NB: wont to do.

Though you've given me a reason to look up the etymology. Now I now: http://www.etymonline.com/index.php?term=wont&allowed_in_fra...

Aaaaagh!

Of course it's more likely that there was a malfunction, no one is saying otherwise, I was just wondering how SpaceX guards their lunch pad from aerial intrusions, hitting a small drone flying fast isn't an easy target and you'd have to have a constant watch for them.

Mostly by being on an Air Force base, many miles away from anywhere someone might operate a "drone". Wouldn't help much against a fixed-wing telepresence rig, but not much would.

The camera is over 4km away, I think its something flying past much closer to the camera.

An insect flying in front of the camera lens. You can see this multiple times throughout the video: 0:54, 4:28, 4:41...

Given the distance between the camera and the rocket, it still could be a bird.

Looks way too fast and round for a bird.. but yeah it's clearly there

It's probably a bug in the foreground of the camera. You can see the same thing at around 1:06 in the bottom half of the frame before it explodes.
