This "tempo" stuff is getting boring. If the crew had 45 mins before they had to go some where else ,then they had bucketloads of fuel, do the maths ie THEY WOULD HAVE HAD THE 60 MINS without alternate.And if they had Tindal (maybe Tempo TS there aswell) they would have been drowning in the stuff. Some should just sit on there hands and think before diving onto your keyboards for a bit of crew bashing.
