OK. I'm game, and its raining, so I don't feel like working on the chicken's fall out shelter... :roll:
Where? What type? Which branch, squadron? Training flight, normal movements, or a special mission?
Military or civil?
You see? While I admire the enthusiasm, this datum simply says 'an airplane flew by', somewhere in the CONUS(?) last night.
Now, if forty people posted something like...
'Geez! there have been 100 C-17's, C-5's and C-130's flew into Ft. Campbell, hung around for 45 minutes, and blasted off en mass'
or
'Every stinking B-2 and B-1 and Tanker in the inventory just cranked up and went hammering out at 50 second intervals!'
That's an unusual movement.
If you are interested in a observation network, or functioning as an observation post, then there are some basic tools.
The Janes aircraft, warships and armoured vehicle recognition field guides(Pocket sized, comprehensive, look in second hand book stores if you don't want to buy new), an air band radio, some WAC charts of your local, the T.C. or FAA pilots supplement book, and track down some of the on-line spotters communities for tips and training.
A Night scope is a great help(cheap, now a days- mine are soviet surplus!) Good binoculars, a field note book. Learn how to file a usable report, like:
(as per FM 7-90)
'SALUTE'
(S)Size of force
(A)Activity
(L)Location
(U)Unit
(T)Time
(E)Equipment
Which is a great report format.
Lastly. Its a great hobby, though most folks would think it a little nutty. That's why 'spotters' are often called 'Anoraks' or 'nutters'.
But don't let that stop you.
And Watch the Sky!
