"And, you run also video because to fly this arm, you're relying mostly on some external camera views that may be coming from the arm itself or from the station."

Previous Quote

A sentimentalist is one who delights to have high and devout emotions stirred whilst reading in an arm-chair, or in a prayer meeting, but he never translates his emotions into action. Consequently a sentimentalist is usually callous, self-centred and selfish, because the emotions he likes to have stirred do not cost him anything.

— Oswald Chambers
