Just on a whim I picked up a Flank Speed booster at the local store. The best possible result would be to pull a second Intrepid. I wanted a second won in order to be able to field a historical 1944-45 USN carrier task group (which generally had two Essex-class CV and two Independence-class CVL). But it looks likely that Intrepids will be highly sought-after in the secondary market and I really didn't want to pay $30 for one ship.
And amazingly a second Intrepid is what I pulled! I think my Flank Speed collection is just about complete.
