I'm afraid 100s of dead were taken in Army trucks to Brookwood, after the exercise on Slapton Sands, Devon, England, was badly planned and also went badly wrong.
When a ship protecting left and enemy vessels opened fire, along with friendly fire and firing of live rounds on our own men to make it realistic, but it was killing them and our men were only training!!

Regarding prices, the only prices I have are for 1940 England, Great Britain and are as follows:-
Funeral Directors (FD) to collect Airmen from two sites at Eastleigh, England and take to RAF Calshot, England in coffins, was £4, 15 shillings (£4.75) each Airman.
Rail Cost in 1940To "Putting on rail" at Eastleigh for a Manchester, England, Burial, it was 10/- (or 10 shillings) 50 new pence / 50 pence extra, making a total of £5, 5 shillings (£5.25 total) with Funeral Directors charges.
Todays Purchasing Power, 2017Using the TNA Calculator £4, 15 shillings in 1940, was £186.90 in 2017.
Although the RAF drove the coffins from the RAF Air Station to the cemetery, supplied a Marching Party, Uniformed pall bearers and supplied an RAF band, per RAF photographs of the funeral.
Grave DiggerI suppose the RAF paid the church separately for the Grave Digger, which is a separate charge anyway, added on top of the Funeral Directors charges today.
