This one sounds simple, but I had a tough time finding it back when it was originally released. Good luck.

Been there , done that. Not as easy as it sounds. Good luck.

If you try for this one at present, it'll be even harder. The Flight servers are apparently down. I couldn't connect for the last hour to check the aerocaches and get the date I collected this one.

Really weird, they were down for me earlier and I decided to check the marketplace one last time and it was up. I had credit so I got the 46 and I logged into the game and nailed the aerocache .

Most of these lately are ones I'm sure I've gotten before, but they're available, so I snag 'em. I distinctly remember this one, very tricky.

Where do get the dates of your previously collected aerocaches?

When you load the aerocache screen there will be a check mark showing that you have collected the AOTD. If you click on the AOTD and look in the right hand corner of the screen, it will show "Date Collected".

HA! Of course. Thanks.

I decided to try something different with this one. Grabbed the Icon, landed in the river a little to the south (or thereabouts) of the aerocache and 'taxied' up the river until I got it.
