> Hitting a drone is your worst nightmare while piloting small aircraft A small GA aircraft hitting a drone has a very high fatality chance, particularly in the stages of flight most likely to encounter amateur drone operators (ie. takeoff and landing).

No, it likely wouldn't have a large effect on the GA aircraft.

? Either you don't know what GA aircraft entails, or you've got a real misconception of the size of a drone compared to a bird.

I am not sure which craft you are talking about flying. Hitting a drone is your worst nightmare while piloting small aircraft? Or hitting a plane is your worst nightmare when flying a drone?

A swan can weigh 8 kilos, a goose can weigh 6, and DJi phantom weighs 1.2 kilos.

Multiple planes crashed with fatalities vecause of birds, as far as I am aware none have done so because of a drone.

The fear of drones had led to pilots reporting drone sightings at 10,000 feet in the middle of the Ocean, thousands of miles from shore.

"Several commenters noted that the AMA analyzed those reported ‘incidents’ and found that out of the 764 reported records, only 27 (or 3.5%) were identified as a near mid-air collision, with nearly all of those involving government-authorized military drones"

A bullet-proof windshield protects the most vulnerable part (the pilot) a lot better than any civilian plane can.

Actually, I'd say the most vulnerable part for a strike in a single engine craft is the engine, which sits ahead of the cabin. At low altitudes there's precious little time to correct for any sort of engine failure.

The P-63 has the engine behind the pilot.

Most (practically all) aircraft do not have bullet-proof windshields (including military), for starters, and secondly a several pound meat ball travelling at closing speeds anywhere between 60kts (GA) to 200+ kts (jets/airliners/mil) is going to do a number on the aircraft regardless if it incapacitated the pilot. Doubly-so if it's a several pound metal ball... You don't want to hit anything in an aircraft, ever.

The P-63 did (example picture [0]), like many others that were designed to attack bombers and/or ground targets.

This seems surprising. Most drones weigh no more than a medium sized bird and are made out of flimsy materials that shatter readily. Sure there might be a bit of fire from the destruction of the battery pack, but nothing that should be a major problem for a GA aircraft. Unless by drone you are talking about a Global Hawk? I would count that as a high fatality risk.

Bulletproof windshields were very common during this period, although 43-11719 doesn't appear to have been fitted with one, likely because the F variant never advanced beyond the prototype stage.

Can you source this? I can't find any information on fatalities due to aircraft-drone collisions, topic of this article notwithstanding.

FWIW, I have a few thousand hours flying jet fighters and have hit rather large birds at high speed (me, not them), and have been hit by rather large caliber bullets (I assume also at high speed). From the two videos, taken at two locations, I cannot positively id a drone. What is described as a sudden altitude change in the second video doesn't look like anything in the first video, though it's mostly blocked by the inconveniently placed large sign. The appearance of a "large altitude change" could be easily explained by the pilot simply easing off the g in the turn to gain visibility, to gain a little speed if it was needed, or sure, to suddenly try to avoid something. It looks exaggerated in the second video I think because the camera is manually tracking something.

hitting a drone is unlikely to cause significant damage unless it hit in just the right spot. Seeing and overreacting to a drone might cause some damage but there is probably one second of altitude change there if any - that collision was already quite likely from the intercept path being flown. I've not flown either of those aircraft (before my time) but looking underneath during a turn requires effort and may not have even been possible, especially if there was a lack of awareness to prompt the look.

I think Juan's youtube video explaining the airborne change of directive from what in the comments on that video appears to have been an under briefed, and sadly under questioned briefing, is by far the most likely explanation.

Any advice for a aspiring fighter jet pilot? (goal is to eventually fly an L39 Albatross)

Well, I've hit birds with wingspans around a dozen feet (didn't go measure). They make a mess, and have killed people I knew, but that was mostly because of their size and the penetration of the windscreen. Hitting a smaller object could certainly cause some damage but it wouldn't likely be immediate and catastrophic unless it was in a critical spot.
