The funny thing here is that these guys don't seem to have understood that they landed at the wrong airport until they couldn't find the appropriate runway turn-off -- and their voices were initially rather nonchalant. Not what you would expect if they had just been standing on the brakes in terror.
What do you suppose the DFDR will say about the landing roll at Jabara? Given that they were expecting to land at McConnell on a 12,000 foot runway (or about 11,000 feet after the touchdown zone), would it be reasonable for them to have planned to apply only moderate braking (or autobraking)?
If that was the case, then might they not be in world of hurt landing on a 6110 foot runway, with maybe only 5000 feet remaining after the touchdown zone? How quickly would they need to realize that the end of the runway was approaching much sooner than expected to get on the brakes in time? Or must they (fortuitiously) have had the autobrake set up for a sharper than normal stop? If so, they were pretty lucky.
