I was in Orlando MCO last Saturday night and had a two hour start up delay due to TS over the field.An Air Transat L1011 pushed back before the ramp was closed and we thought departed.When we finally got going he was at the stop end of 36R with all the chutes deployed which meant that 36L was the only runway being used.17/35 was not being used due to the weather.I counted approx 25 aircraft waiting to go.Lightning strike causing smoke ?? Anybody know what was wrong.
