Tightslot,
I know about the evacuation in 90 seconds and so on. But, me memeory serves me very well. Several years ago, before EZY et.al., airlines like BA did NOT have a row of seats over the wing exits at all. Due, I guess to increased cost pressures, seats were added in, and so now there are rows of seats at over wing exits on most airlines.
In fact, the history was, I think like this, the British airtours Manchester runway disaster highlighted the difficulties of escape from wing exits, and this then lead to overwing exit rows being removed completely. Following on from this over several years, airlines gradually decided those rows should really still be there (for financial reasons), and put them back in, with a marginally bigger gap between the rows.
Nobody will ever convince me that putting a row of seats adjacent to an overwing exit is a good idea.
Until it changes, i will be re-assured to know that pax safety is NOT the main concern of any airline. Making a profit is.
