Starting on 1 december till 31 december 24.00.
You have 20 minutes working time to make 6 launches. You must try to fly 3, 4 and 5 minutes flights in this order (not necessarily in succession), these are maximum flight times. You are allowed to restart in order to make the required time but you may launch only 6 times in total.
Try to make a 3 minute flight, you do not have to make the 3 minutes but that time will be lost in the total score. Next try a 4 minute flight, you have a total of 3 spare launches so you can retry. Finally try the 5 minutes.
Flight 1: 170 seconds
Flight 2: 90 seconds
Flight 3: 245 seconds
Flight 4: 70 seconds
Flight 5: 78 seconds
Flight 6: 300 seconds
The total for this task = 170 + 240 + 300 = 710 seconds
The last flown time should be sent to firstname.lastname@example.org within a day after flying the task
The best time gets 1000 points
Theoretically it is possible to fly 720 seconds
If someone did make 720 seconds (1000 points) and you did 710, then your score is (710/720)*1000 = 986 points
