I shot down a UFO, but a few of my "must have" soldiers are recovering from wounds. I would like to send them in 4 days, or 2 if I had to. Will the crash site disappear or otherwise go bad if I wait too long? If so, how long is too long?

  • why not take this opportunity to train up some rookies? :) – l I Oct 12 '12 at 12:34
  • @spartacus I've had this happen when I was waiting for the rookies to arrive (it was either wait or send out a 2 man squad :\ ) – therefromhere Nov 3 '12 at 22:00

These are the timers for all game modes in hours taken from game data:

    This is very useful info! Is there also a timer for how long you have to shoot down a flying UFO? – Elbyron Nov 7 '12 at 18:38

    Just to add expansion info : These times are unchanged in Enemy Within. – Flyto Dec 7 '13 at 10:43

Based on some testing:

  1. On Normal, I have observed several of scout-classed UFOs take between 24 and 48 hours before being "repaired" and disappearing.

  2. On classic, I have observed two scout-classed UFOs taking between 24 an 30+ hours to disappear.

Small sample sizes, and I don't know if bigger ships are more or less likely to take off quickly.

  • I'm playing on NORMAL with ironman and a medium crash site just vanished in about 17 hours. Dammit! So the advice of 24-48 is not accurate. – user41039 Jan 17 '13 at 3:49
