Pretty remarkable, and beautiful plane, but I think it had some major flaws:
1.) Expensive
2.) High Maintenance (as some beautiful women are)
3.) Swilled fuel like a drunk sailor
As an example of how the plane suffered...
The power supply to the radar was under the ejection seat. To pull the power supply, you had to pull the ejection seat. (EOD qualified technician required). To apply power, the ejection seat had to be reinstalled. MTBF for the powersupply was on the order of 10 hours. The rest of the radar MTBF was also on the order of 10 hours.
There was a large weight that had to be suspended from the nose if the fuel was emptied. If you forgot that, it would rear up on its back legs.
