@F104Deathtrap Mate i dont know where you get your facts from but they are completely wrong ?? if you say the xb-70 was so fine why in 1965 did AV1 engine intake ramp brake off in flight damaging all the engines beyond repair and in the same year while surpassing mach3 the panels on the xb70 brake off due to heat and stress and caused the left wing to be left missing in flight. So they had to limit the xb70 to mach 2.5. The program cost 1.5 billion and they only ever built two. look it up lol and Saunders Roe 177 rocket jet fighter was tested with the SR53 and performed perfectly and had no problems. It would have used hawker red top misslies and a interception radar. The SR 53 did not have these because it was a prototype lol lack of funding and dirty dealing with lockeed and germany caused the 177 not to be built. and we did use the ee lightning up to 1988 and then we used the f4 phantom but only til 1992 but it was nothing compared to our tornado GR4 which is faster and better armed and is still in service unlike your f4 phantom lol and look up when america was trying to ban concord from coming to new york in the 70s. America wanted to make there own concord but to build a bigger and faster one which was technically impossible at the time btw before you comment look up your facts first try wiki lol.
@F104Deathtrap why you sent me a youtube link lol just accept your wrong i have checked every bit of imformation what i have sent to you and its all right if you dont believe look it all up on wiki
@F104Deathtrap Your forgetting who run all the funding for the UN. It was abit strange why we couldnt get funding for the tsr2 or the Saunders-Roe SR.177 which was strangely replaced by the american f-104 when the SR177 had superior performance to the f-104.The Saunders-Roe SR.177 would have even out performed the ee lighting due to its rocket jet engine and america only cancelled the xb 70 bomber because it had list long of problems lol but dont forget concord which was funded by the english and french and was able to be made in perfect success and the americans hated it that much they wanted to build there own.
