About 310pm pst , while sitting in the backyard (binoculars at the
ready) an unfamiliar sound filled the air. Combo if a high pitch plus
big base. The outline in the hazy skies resolved into a high wing
(slightly swept), t-tailed 4 engine a/c headed north east from long
beach, cal. Nothing on flight aware and not on flight radar . Sure
wan't any US of aye standard stock ac. Some joint exercises? Lat time
I had a different sounfd get my attention twas a volga dneiper IL-76
out of LAX. That was shown on flightradar... Thoughts?
Some thoughts =
I live north of Seattle, about 5 miles from Paine Airport
near it's flight path,
KPAE - Snohomish County Airport (Paine Field)
Huge Boeing plant there.
We see plenty of flights from the big Dreamlifter,
and also the huge Russian cargo carriers.
Antonov An-124 &
They show and identify on the map, the vast majority
of planes - scheduled, & private, & leisure flights.
Fairly often I have seen what I thought was a
military plane, and it has not shown up!
Also one time a B-17 was in for a show,
and it did not show up.
I do not know what the reasons are.
This clarifies one aspect I thought:
For security and privacy reasons information about some aircraft
is limited or blocked. This includes most military aircraft and
certain high profile aircraft, like Air Force One."
"Aircraft visible on Flightradar24 (within ADS-B coverage)
When ADS-B was initially launched, it was primarily used in
commercial passenger aircraft with 100+ passengers. An increasing
number of aircraft including smaller aircraft types, are
getting ADS-B transponders but, until ADS-B becomes mandatory
it's up to the aircraft producer and owner to decide if an
ADS-B transponder should be installed or not."
So, it sounds like the WWII era aircraft I've seen
just do not have these transponders.
