Maybe it's a new Santa, and he's practicing for the big day.

The same data, date vs. altitude. The letter is the severity, 'A' being the worst.

Cheers Steve, sounds better. I take your point, up front of one of those things. Birds you can't do much about, plastic bags are of no interest. And then you get the possibility of a drone gets on the agenda. Will make you wish that possibility would go away. And you see some things wrongly. Reckon I would.

Plastic bags ARE of interest Don. Ingested into an engine, they melt and can block vital cooling holes in turbine blades etc.

I was in the 80's flying a 30 foot span microlight and had a near miss with two RAF hawk jets. It was close enough for me to the pilot of the nearest aircraft gripping his stick and the backseater looking at his clipboard.

As Chris notes from the time I saw dot's in the sky to them passing was no more than five seconds.They did not see me.

In an era where it is possible for boys to have periods, as nowis to be taught in some schools, where one cash strapped authority is to install disposal devices in the male toilets. It seems that however improbable something is, you are very brave to challenge the improbable.

I imagine this places many, particularly the BMFA in a position, where even if the report seems most improbable, that it is politically desirable to at best stay silent. Anything else would risk that some would say that they do not take the issue seriously. Deniers, perhaps having some type of phobia.

I now await the verified report of a hobby quad at 30, 000 feet, and traveling at mach 2. Even the manufacturers name was clearly seen.

Erfolg you should try reading the bible , early on it suggests that their is an almighty power that only a special few with superior eye sight have seen. Yet it accepted that this power does indeed exist, yet higher than 30000 feet with no known manufacturing details,

I for one have no issue at 500 knots spotting and identifying objects and have indeed seen interesting things at these speeds that have been reported and verified by the military.

Good luck with your imagination .

This thread has changed from "Can a drone fly at 10000ft?" to "Can a pilot identify a drone whilst flying an aircraft". The former technical question has been near enough answered but the latter observational question has not, even though there is a lot of supporting comments suggesting he can't"

Even though many would be quick to dismiss it, I would very much like to see an official CAA response regarding the latter question, or perhaps an official BMFA response.

It is well documented that it is very difficult to pick out another aircraft - or drone - whilst flying, the UK Airprox Board has several documents outlining the physiology and techniques that can be applied to help mitigate the problem. We teach these from lesson 1 for full size.

However once an object has been spotted the eye & brain are good at identifying it - as my earlier post illustrated & for example as JD8 observed above he could see the stick & clipboard in an opposite direction fast jet.

Now they are blaming chinese lanterns for a near miss!   This time it was 20,000ft and Cambridgeshire  ( see Daily Mail website)

I was once responding to a Coasguard call out about possible UFO's being seen over the town and was talking to the first informant on the main street when Batman and Wonderwoman came strolling up the road [ a real fools and horses moment laugh ] I asked Batman had he seen anything to be informed that idiots were launching chinese lanterns down at the sea front.

That is the 'A' at 20,000ft on the graph that I posted a couple of days ago (airprox 2018203).

I doubt if the the CAA would make an explicit statement that the don't believe some of the reports from commercial pilots, but there are hints in some of the documents that have been published over the last few years.

From John Lee, "However once an object has been spotted the eye & brain are good at identifying it - as my earlier post illustrated & for example as JD8 observed above he could see the stick & clipboard in an opposite direction fast jet."

the brain has very fast and clever pattern recognition systems. But it recognises patterns, but can gives false positives, and false negatives. Have you never stared at something, and not been able to work out what it is, then you get a mental flip, and you see what it is. Or seeing the man on the moon.

If the brain says it's a drone at first "seeing", you believe it, and if it's gone in seconds, you never worked out what is was, and it's a drone

Yes, mistakes can be made and no doubt there are errors in some of the reports.

However all the reports are scrutinised by the UK Airprox board (linked above) which is comprised of 14 experienced practitioners plus a number of expert advisors and undergo a rigorous causal analysis & risk assessment before the results are published. I'm inclined to take their output seriously.

So do I. And I point out, as mentioned above, you were not there, I was not there, and the board members were not there.

I am sure that is the case for manned/manned airproxes and manned/unmanned where there is a report from the SUA pilot. It has been pretty obvious that it is not the case for manned/unmanned airproxes where the only information is an eyewitness report from the manned aircrew since the report format for these changed in May '17.

All flights out of Gatwick tonight cancelled due to a "drone" on the runway. What do you reckon it's a pigeon?

Some very seriously naive people on here and also irresponsible as well. The airport has no option but to stop transit through its airspace once reported, The results otherwise don't really need explaining,

The fact is is that their are people who are flying quads into Controlled airspace knowingly to get some good shots? and yes it is people with DJI inspires and expensive quads too,

Apparently its been flying for 11 hours now, must be powered by nuclear fusion.
