Landing gear raising question
Spending many a Sunday watching aircraft comming and going at fajs I noticed a SAA Airbus A319 take approximateley 3 minutes before he raised his gear after take off.He must have climbed at least 3 thousand feet before he decided to raise his gear.This is not normal,did he forget I wonder as I doubt there was a problem as he seemed to proceed toward his destination as I know the standard routes traveled.Any Comments?
