The Messerschmitt M 28 was a mail plane developed in Germany in the early 1930s to meet a requirement by Deutsche Luft Hansa.[1][2] It was a single-engine, low-wing cantilever monoplane of conventional design with an enclosed cockpit and fixed, tailskid undercarriage. Despite successful trials, Luft Hansa changed its requirement and did not purchase the design, due possibly at least partly to the enmity of Luft Hansa director Erhard Milch towards Messerschmitt.[3] This would be Messerschmitt's final attempt to market a commercial aircraft in Germany (the Messerschmitt M 36 was designed specifically for Romania), with the company subsequently returning to the production of sport aircraft instead.[3] Specifications{{aerospecs|ref= |met or eng?=met |crew=two |capacity= |length m=10.00 |length ft=32 |length in=10 |span m=15.50 |span ft=50 |span in=10 |width m= |width ft= |width in= |height m=3.00 |height ft=9 |height in=10 |wing area sqm=25.6 |wing area sqft=275 |empty weight kg=1,480 |empty weight lb=3,260 |gross weight kg=3,000 |gross weight lb=6,600 |eng1 number=1 |eng1 type=BMW-built Pratt & Whitney Hornet |eng1 kw=390 |eng1 hp=525 |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |max speed kmh=260 |max speed mph=160 |cruise speed kmh= |cruise speed mph= |stall speed kmh= |stall speed mph= |range km=2,450 |range miles=1,530 |endurance h= |endurance min= |ceiling m=5,200 |ceiling ft=17,000 |climb rate ms= |climb rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} Notes1. ^Taylor 1989, 651 2. ^The Illustrated Encyclopedia of Aircraft, 2460 3. ^1 Szegeti 1998, 74 References{{commons category|Messerschmitt civil aircraft}}
