I saw this in a documentary many years ago as some sort of spy aircraft to exfil from a hostile country.
While a cool concept, subsequent ultralight aircraft made this design obsolete.
Just don't get shot at or have a leak. While it could be very compact to transport, it's not very practical or robust.
Also, the service ceiling and service floor(?) could vary based on temperature. For example, if it started at sea level and very cold conditions, it's possible it could not exceed a certain altitude below the need for a pressurized cabin and below its performance coffin corner.
It says because of the airflow from the engine it could be punctured by up to 6 .30 calibre bullets and maintain pressure. Is this enough resilience? (I don't really know about aircraft combat)
