We must have been on steroids in MMA.
Regularly and as a "requirement" FL 200 DRB-PER or PER-DRB on the schedule, took a little skill and daring so to speak and heavy usually.
220 Kts is my recolection as well, 5.5 hrs-6.0 hrs from my log book 1972 for those legs.
Good fun and good days, pity they have gone in the mess the industry is now.
