There are 2 daily flights, one leaves at 0745, returning 1345. The other flight leaves at 1700, but is down as returning 08:30 the next day. The latter may change as thats a long night stop at MAD, unless they plan to operate a W-pattern to somewhere else.
Not really. 1700 departure will arrive in MAD at around 2015. Perfect timings for a nightstop when the same crew will be operating the 0830. Remember the crew will need 11 hours rest.
