Indian Airlines. By John Stroud. Esso Air-World Volume II, Number 4, January / February 1959.
Two articles from The Illustrated weekly of India, December 9, 1973, which candidly report the sorry state of affairs in the airline at the time, and the tough stand taken by the new Chairman, Air Chief Marshal P. C. Lal in dealing with the situation. (While the first article is complete, only the first page of the second is available here – our apologies)
