"senior hardware technical support executive" "I take these master degrees as an entry ticket to the aviation industry"
Wow, my position may not apply to your region, but a masters degree to gain a entry level position in the aviaton industry from my position in north america sounds rediculous.
Technical specific training, possibly AS/BS accreditedis great. Most here only seek a MBA for goals in upper MGT, "director/VP"..
Seems to me a career student could do much better in study for a masters degree in many other fields than aviation. The odds are against you in this industry. Nepotism and sutch are far more valuable.
