Web SDRs
Even if your local noise level is high, you can still take a look at the HF bands by using a web based SDR RX. A good place to start is http://www.websdr.org/ . This has links to many SDR receivers around the world, so you can even listen to the bands as if you were elsewhere on the planet.
Webpage about 2m FT8
On my main website is a page about 2m FT8. This mode has transformed 2m. There is probably less SSB and CW operation, but every day, irrespective of conditions, DX that was previously unimaginable with QRP becomes possible. Almost without fail my QRP is copied at any time in Cornwall and Northern Ireland. This seems more like "flat band" tropo than aircraft, which would only work at certain times.

80m chirps?
Southgate News has a report from the IARU about odd chirps that have recently appeared on 80m.

2m FT8
Although I have been on 2m FT8 overnight there are no spots yet this morning.
UPDATE 0935z: So far 24 stations in 6 countries spotted on 2m FT8 with best DX being DK1FG (815km).
UPDATE 1205z: A recent 2m FT8 CQ (2.5W to the big-wheel omni antenna) was spotted by 7 stations. G1BHM (355km) in Devon was worked. In all 33 stations spotted today on 2m FT8 RX.
UPDATE 1229z: As an experiment, I set the FT817ND to 500mW and called FT8 CQ. I was still copied by 3 stations with the best being G1BHM (355km) in Devon. With 2m FT8, you definitely do not need high power or big beams! On 2m FT8 RX, 35 stations spotted so far today.
UPDATE 1326z: Now 37 stations spotted here today on 2m FT8 RX with the big wheel.
UPDATE 1712z: Now 58 stations in 8 countries spotted so far today using the FT817ND and the big-wheel omni antenna. The maps shows the stations so far received today on 2m FT8 RX.

Mechanical TV in the 21st century
When TV first appeared it was a 30 line mechanical system pioneered by John Logie Baird. These days there are still 30 line TV enthusiasts, although now PCs can be used to do line conversion and reception.

The mystery of consciousness - NOT amateur radio
All humans are conscious beings who can contemplate our pasts and futures. We do not know about other animals. As it is highly likely we evolved from animal species, it highly probable (at least) some animals are conscious and aware of themselves as we humans are.
In all the vastness of our observable universe, we are here on this planet at this time.
At some point in the future we may be able to explain what consciousness is. For now, it remains a total mystery. Is it linked to our physical body?

2m FT8
OK, I admit it. I am lazy!
As it saved unplugging the lead from my SignaLink USB to the rig, I went on 2m FT8 using the FT817ND rather than the FT991A, so power was 2.5W. Even so, my brief FT8 CQ was spotted by 5 stations with best being GI6ATZ (479km) in N. Ireland at -16dB S/N. G7RAU (461km) in Cornwall seems to spot me every time! I should try with 100mW to see if he still spots me!
On 2m FT8 RX the best station spotted here was G1BHM (355km). Again, I am just using the big-wheel omni antenna.
UPDATE 1528z: Now 19 stations in 6 countries spotted on 2m FT8 RX in the last few hours.
UPDATE 1606z: Now 22 stations in 6 countries spotted so far this afternoon on 2m FT8 RX. My very recent 2.5W FT8 CQ was again spotted in N. Ireland and Cornwall. I am sure the 43 element at G7RAU must help!
UPDATE 2002z: Now 37 stations in 8 countries spotted in the last 5 hours on 2m FT8 RX using the FT817ND and the big-wheel omni antenna. Best DX today on 2m FT8 RX is DK6JU (529km).

Summer migrant birds - NOT amateur radio
At the end of September we visited our son near Canterbury. There were plenty of young swallows overhead getting ready to migrate south. Already most of the summer migrants have flown south. By now most have gone. It will be March or April next year before we see them again.
