Hi all,

In addition to the regular hazard zones near the launch site (and one 800 km
downrange, I noted another area warning for the Atlantic related to the SpaceX
Dragon CRS-15 launch.

This one interestingly enough runs from 29 Jun 15:53 TO 29 Jun 16:32 UT, :

WESTERN NORTH ATLANTIC.
1. HAZARDOUS OPERATIONS, SPACE DEBRIS
291553Z TO 291632Z JUN, ALTERNATE
301531Z TO 301634Z JUN AND
011504Z TO 011543Z JUL IN AREA BOUND BY
39-33N 059-40W, 28-00N 046-28W,
22-27N 051-52W, 34-46N 065-09W.
2. CANCEL THIS MSG 011643Z JUL 18.//

Authority: EASTERN RANGE 271908Z JUN 18.


It appears to delimit a deorbit area, some 6h20m after launch, i.e. about 4
revolutions after the launch.

That is oddly long after the launch moment, so to me it looks like they are
experimenting with something. Anyone any clues? Maybe in connection to ideas
floated about about upper stage recovery?
