Not so far
. The technical leap to orbital missions will be most interesting. I'm aware that the Megaroc maximum terminal altitude was estimated at over 1,000,000 ft, but you could quibble whether only that would really constitute the (first suborbital) formal human entry into space, or whether that threshold might actually already have been crossed on one of the preceding test flights during gradual envelope expansion, e.g. when reaching the Kármán Line (although it was only postulated in 1959) or another similar limit, see alternatives at
okay, we got the TRL series for the BIC Winged Orbital Rocket:
mid-1948: The Ministry of supply issues the BIC with Specification X.9/48 - An orbital glider capable of Orbital Photo-recon and scientific payloads and experiments (TRL1)
Late 1948: A rough design for the glider and booster is completed by the BIC design board, with a design brief held with Bristol Aviation for the Glider itself, Normalair for the glider's air conditioning systems, and Avro for the construction of the booster. (TRL2)
March 1949: The design for the glider itself is finalised, and delivered to Bristol Aviation works, after thorough investigation of the proof-of-concept design. The BIC expects a mock-up of the design to be completed by the end of the year, and delivered to the RRE for crew-training and evaluation. (TRL3)
Summer 1949: Avro reports difficulties in the design of the booster, and so the design is altered to a 5-stage to orbit design that can be manufactured in time for the launch deadline of Summer 1951 (TRL3)
August 1949: a 1/3 scale model of the Glider is delivered by Bristol to the RRE for evaluation in wind tunnel and heating tests. It performs admirably in the Wind Tunnel Tests, however it underperforms in the Heating tests, and so a contract is issued to Turner And Newall for steel-lined asbestos lined tiles to increase the Glider's heating performance (TRL4)
November 1949: Bristol delivers a full-size prototype of the glider for vacuum tests and fuelling tests, which it excels at. The glider is now given the Winged Orbital Rocket designation by the BIC, with Bristol designating it as the Bristol type 244 Polestar, of which was to become its unofficial name (TRL5)
December 1949 - April 1950: Avro delivers each rocket stage it has completed for evaluation over a period 5 months, with the first stage being delivered on 10th December, and the 5th stage being delivered on April 4th. All are tested and test-fired as soon as was possible after their arrival. (TRL6)
February 1950: The glider, manned by Eric Winkle Brown and Ben Gunn, is towed by the BIC's lancaster to an altitude of 10 miles, and is released to fly as a rocket plane, climbing to an altitude of some 60 miles above the earth, setting a new world speed record at mach 4 as it did so. (TRL7)
November 1950: once the rocket booster stages have been test-fired and the glider approved by the Air Ministry for manned flight, a tele-controlled orbital flight is made on the 1st of november, after weather delays postponed the flight from its target date of the 25th of october. The flight is near flawless, but in the last leg of reentry, radio contact is lost, however the craft survives. It was not decided whether this was a natural phenomena, or an equipment failure, so the flight is repeated the following month, to the same results.
May 1951: After extensive training, two astronauts fly the craft up to a 200km by a 189km orbit, for a period of 16 hours, and then they return to earth. (TRL10)
