What difference occurs at 12,000 ft. "in your book"?


You lose much of the GA fleet at 12,000 ft. The sky gets that much bigger.

TO HIT THE HAWKER 800XP, zipping past:

60 mph = 88 ft/sec
600 mph = 880 ft/sec

300 mph = 440 ft/sec
+20%
360 mph = 528 ft/sec = 10 Hawkers @ 52' long, each.

Or one (52 ft long) Hawker travels 52 ft, in a tenth of a second.


TO HIT THE GLIDER - in the crosswalk:

He's 22 ft long
60 mph = 88 ft/sec

After 1 second, his tail is at 66 ft. His nose is at 88 ft. He's safe.
(That's 14 ft clear of the Hawker's 52 ft wingspan)

After 3/4 of a second, that would still leave 8 ft of the glider's tail
exposed, to the Hawker's wing.
(We'll call it one second to get through the crosswalk)

One second one direction and 1/10th of a second the other direction - on a
two dimensional plane at 13,000 ft.

"My book" calls that ...blame the meteor.

And it's a very good book.
