No aircraft flying between Bikini and Enewetak encountered airborne

Subsequent Wilson flights were cancelled.
Based on a helicopter preliminary damage and radsafe survey at] approximately H+2, all units of the task force were issued an advisory drective
as follows

Upon confirmation of reentry hour, all units reenter
Eneu anchorages in accordance with previous
instructions.

The results of the preliminary survey indicated that Bokbata,
’
Enidrik, and Bikini islands and the Iroij-Aomen chain were contaminated.
Lagoon contamination was restricted to a V-shaped pattern with the
Eneman and tips covering the Bokbata-Aomen area.

Reentry and recovery occurred largely on shot day.
