It so happened that the aviation chief at the very moment was headed for the hangars. He was accompanied by two officers of apparent high rank, who gave the various types of aircraft close and critical inspection.
When the No. 3's came to their notice, one of the officers, a grizzled veteran, with a livid scar showing from temple to chin, halted with a pointed word of commendation.
"There's speed, balance and strength for you. Where were they built?"
The aviation chief explained.
"Ah, I see," said the officer, "the paint only is ours. Well, I think we need look no further. Get them ready for immediate use. Where are the pilots for this assignment?"
A call was passed for Billy and Henri.
When they faced the official visitors, both of the latter turned a stare full of question marks at the aviation chief.
"Are these the sons of our pilots to be?"
The senior colonel meant to be a bit sarcastic.
