Pilots report increased near-collisions with drones

Air flight is relatively safe. At least, about as safe as flying through the air at hundreds of knots, thousands of feet up, in a fragile aluminium tube, carrying many gallons of flammable fuel, with an on-board ignition sources (electronic system & engine), can be.

Actually, the most dangerous parts are taking off &, most of all, landing. Which is why most air crashes occur at airports.

See image above.

Why is aviation relatively safe?
• participants put their life on the line
• barriers to entry are high: aircraft are expensive, pilot training is both expensive & time consuming
• very tightly regulated
• if you do something wrong, sooner or later you have to come back down, at one of few landing spots, & face the music

None of the above applies to the rapidly growing drone market. Regulations are rudimentary & difficult to enforce. In the USA there is a, “not above 400 feet, not within 5 miles of an airport”, rule. It is not always observed (placing aircraft at risk when they are most vulnerable – see links below), & doesn’t apply to areas such as hospitals, where rescue helicopters have to land from time-to-time. Another at-risk area is fire-bombing sites.
