1200 miles? Sir should consider the A-35B Vengeance; max speed 230mph, normal range 2,300 miles!
I can see that Sir is looking a little askance, but I can assure him that these figures appear in 'Combat Aircraft of World War Two' and can further assure him that these are the figures in the Vultee brochure itself! So perhaps upon reconsideration Sir would like to have a test flight? With that mighty 1700hp Wright R-2600-13 roaring away in front, Sir will realise what a tremendous improvement this model is on previous ones! Did Sir have any particular colour scheme in mind?
