The US Air Force says its scientists have identified the root cause of the hypoxia-like events occured in its F-22A Raptor stealth fighters and linked the issue with the supply of oxygen delivered to pilots, not the quality of oxygen they were breathing. Two changes are being implemented to correct the oxygen supply issue - removing a diagnostic filter to increasing the air flow, and foregoing with the high altitude pressure suite, suspected to cause some of the problems.
If Washington is really serious about moving forward in cooperative development with India, it should give up on MMRCA; its goal should be partnering and joining the Advanced medium Combat Aircraft (AMCA), a single seat stealthy jet to replace the Jaguar and MiG-27s by the turn of the next decade.
