Amazing? *Yes, but not unheard of.
Frank Luke got 18 victories in about 20 days. *Indra Lal Roy, the only Indian ace to date, got 10 victories in 13 days. *
George McElroy had a period where he got 13 victories in 16 days. *
Ray Collishaw had 10 within an 11 day period. *
And look at what several German pilots did in the month of April 1917.
As for Squadron leaders who were not supposed to fly, Mannock took over 85 after Bishop, and he still flew. In fact, I think it's safe to say that had Mannock NOT flown, he would have survived the war.
Just something more to think about.
