A bit more on the He 211 (and some very ugly artwork from Der Spiegel).
Flight, June 1963: Lufthansa wanted this "twin [GE] CF700, 24,250lb, 540/m.p.h. aircraft on German domestic services where their small size (32 facing inward or 22 conventionally placed) and high speed will permit close matching to fluctuating traffic on different routes without sacrificing utilization".
The He 211 began as a turboprop DC-3 replacement concept in 1959 (Flight, 22 March 1962, other sources say design began in 1958). The He211A-1 was the turboprop, the He 211B-1 was the jet.
He-211B-1 specs (from the Flugzeug Forum):
Crew: 2 Passengers: 22-24
Engines: 2x GE CF 700 (circular intake near Y-tail)
Take-off weight 10,965 kg
Cruising speed 840-872 km/h
Range 780 - 2080km*
* According to Die Zeit, 16.03.1962 Nr.11 ("Weltmarktchance für Heinkel?), range would be only 1150 km (with reserve). Die Zeit goes on to say that the He 211 would be able to operate from 650 m grass runways. Cruising speed is given as 872 km/h at 8000 m.
It looks like the German government decided to fund the VFW 614 instead.
