EWAS reports that the first wave will depart at 0900LT. And since the drops are at 0930LT and 1130LT, my guess is the second 'mission' will depart Eindhoven at around 1100LT.
Present at this time are:
1x RAF Dakota
3x USAFE C-130J-30 'RS'
1x Lw C.160D
1x RAF Hercules still expected to arrive in the early morning of the 18th
Have fun in the (hopefully...) sun!
