Parkgate Crescent lies directly under the 22 climbout from the City Airport and could have been subject to wake turbulence from the impressive display of the Airbus.
Hopefully here is a link to an article about wake turbulence illustrating the effects and dangers that can be caused.
Thats true .... The A380's wake turnulence could of already made them loose and then a RYANAIR / FLYBE or FLY BMI flight just made them looser and then the flew off.
