start ups
Same two above ,although 963 has those namby pamby exhausts and not the old "fishtails"!What a noise as the engines were run up for mag drops etc!!!Hunter Avpin starts,never had one explode on me but often had a lung full of fumes!How about the Hercules,lots of smoke there also!!!My hearing has never been the same since and for those who may be in the same industry a commercial gas turbine as used in power stations can also make a lot of noise!!!
