Is that '45 seconds' special African time, a bit like an engineer's 'it'll be ready in 30 minutes'?
How I hate those...
Nope.
It's adding 25 to 30 liters to make the trip up the mountain and back down with max. load at 15000+ft DA.
Max fuel = 120lbs on the clock, roundtrip time = 9.5 to 11 minutes.
