wasnt Eastern the launch customer for the 757?

I have three memories of Eastern Airlines:

1.  The first and second flights I'd ever been on, the first CLE-RSW and the second MCO-CLE (I don't know if we stopped in Atlanta on either flight).

2.  When we were scheduled to fly on Piedmont, MCO-CLT-EWR.  Charlotte was fogged in, so we were reticketed on an Eastern flight.  Then Eastern cancelled all of their flights to New York/Newark (mostly on DC-9s) and decided instead to bring an L-1011 down from JFK "to get as many as you [passengers] up to New York as possible."  Six hours later (after the three hour flight down plus refueling, etc.) My family sat in the very last row without recline... and this was when there were still smoking sections at the rear.  Good: back in NYC three hours later; Not so good: need ground transportation to EWR where our car was parked; Bad: arriving at JFK's international terminal at 2 AM when it was pretty empty; Worse: we had to play hide-and-go-seek in order to get our voucher and taxi; Worst (or best): getting home at 4 AM and missing school because we were totally exhausted.

3.  The horrid "Trip from Hell I" flying Eastern Express on a puddle-jumper PBI-JAX, landing in a severe thunderstorm, finding out that we flew through a tornadic supercell, waiting for our delayed flight JAX-EWR, and having aviaphobia for years because of the experience.
