B-707
Should it make me feel old to have worked on a 707, only 34 but it makes me wonder how many other people younger than myself have had the experience of working on or flying this majestic aircraft...
My experience was with a CAC.. Challenge Air Cargo bird that cracked a wing spar, after months of tear down and some fine sheetmetal repairs (not my skillset) she flew again only to suffer another hard landing that put her down again.
There are probably a bunch of old folks here who remember her in her glory as the first of few JET AIRLINERS. The 707 and DC8 did alot for me in understanding the basic systems and how they have evolved onto the commercial aircraft of today.
Our common reference today to a classic aircraft is most commonly the the 737/747 only because they have advanced in structural improvements that are competative in the market.
