Boys:
1. Fixed u/c
2. American - no!
3. Lysanderish? - mm, yes, but very "ish"!
I will say, in fairness, that this is a prototype. The second prototype was different and had semi-retracting u/c. Prod aircraft retracted fully. The later machine (past the 1st prototype) were also different in many other ways!
