Defenitely..There will be more failures since we try to develop new missiles or perfect the existing technology.We announce missile tests prior the test unlike pakistan(if u think you know the reason why),and we are not ashamed to announce our failures.That attittude made us surge ahead with successfull Agni2,Agni3,Akash,brahmos,ASTRA,NAG,KL15,Shourya,AAD,PAD,dozens of our own military and non military satellites placed on orbit by our own rockets etc.
Also remember that indian rockets have reached moon(some 384403 km away),holds the world record of launching 10 satellites in single launch,while pakistan is yet to launch its very first slv.By seeing where we have reached now,we are sure all our failures have helped reach us much ahead in rocketry than the nation who never had a failure.
India have more than once successfully tested Agni3,Agni2,Shourya,Brahmos,Akash,Nag,AAD etc in last two years.Was there a retaliation from pakitan by testing similar missiles,following indian tests?
